Rare Right Ventricular Calcified Amorphous Tumor Mimicking Malignancy: A Case Report.

BACKGROUND Cardiac calcified amorphous tumor (CCAT), a peculiar and uncommon non-neoplastic cardiac lesion, was initially characterized by Reynolds and colleagues in the medical literature in 1997. This distinctive entity is hallmarked by its unique feature of pedunculated and diffused calcifications, primarily infiltrating the cardiac structures, with a predilection for the mitral valve annulus initially, followed in sequence by the right atrium, right ventricle, left atrium, left ventricle, and tricuspid valve annulus. The nature of CCATs, despite being benign, poses diagnostic dilemmas, as they frequently masquerade as malignant tumors due to their clinical presentations, which resemble those caused by potential complications such as obstructive masses and thromboembolic events. CASE REPORT A 50-year-old man presented to our hospital with shortness of breath. He had been short of breath for more than 5 years after repeated activities. Transthoracic echocardiography showed a mobile high echogenic mass from the middle of the right ventricular wall and pericardial effusion and right heart insufficiency. The electrocardiogram (ECG) results demonstrated a sinus rhythm, complete right bundle branch block, and T-wave alterations. Additionally, the chest computed tomography (CT) scan revealed a slightly enlarged heart with a lack of density and calcification in the right ventricle. He had an uneventful postoperative recovery after the resection of the cardiac tumor. The mass had not continued to grow when we compared it with preoperative cardiac color doppler echocardiography, after 3 months follow-up. CONCLUSIONS CCAT is a rare non-neoplastic cardiac entity. Diagnosis of CCAT poses a challenge due to the absence of distinct clinical features and its frequent misidentification as a malignant tumor mimic. Surgical resection serves as the sole treatment for symptom relief.

Progressive calcification of bioprosthetic mitral valve observed during pregnancy resulting from in vitro fertilization: a case report.

BACKGROUND: Women with pre-existing cardiac conditions who undergo assisted reproductive technologies (ART) are believed to be at a heightened risk of cardiovascular events during both the treatment and pregnancy phases. An unresolved question within this context pertains to whether the ART procedure itself constitutes a risk factor for individuals with bioprosthetic heart valves (BHV). Additionally, there is ongoing controversy regarding whether pregnancies expedite the process of structural valve degeneration (SVD) in BHV. The purpose of this study is to present the developmental process of BHV calcification, which is considered the primary cause of SVD, during a pregnancy resulting from in vitro fertilization and embryo transfer (IVF-ET), an ART modality, and to elucidate the underlying mechanisms. CASE PRESENTATION: At 7 + 3 weeks of gestation in a twin pregnancy resulting from IVF-ET, a 27-year-old woman with a bioprosthetic mitral valve manifesting severe mitral stenosis and moderate pulmonary arterial hypertension, was suspected of SVD. Despite undergoing fetal reduction, she experienced progressive calcification of the bioprosthetic valve, increasing pulmonary arterial pressure and ultimately deteriorated into heart failure. An elective cesarean section and redo valve replacement was subsequently administered to improve her cardiovascular condition. As a result, a healthy young boy was delivered and the dysfunctional BHV was replaced with a mechanical valve. She did not report any discomfort during the 3-month follow-up. CONCLUSION: The progressive calcification of the BHV was observed during IVF pregnancy, indicating a potential connection between fertility therapy, pregnancy and calcification of BHV. Pregnant women with pre-implanted BHV should be treated with caution, as any medical interventions during ART and pregnancy can have a significant impact on both maternal and fetal outcomes. Thus, involving a multidisciplinary team in decision-making early on, starting from the treatment of the original heart disease, throughout the entire process of ART and pregnancy, is crucial.

Outcomes Following Transcatheter Mitral Valve Replacement Using Dedicated Devices in Patients With Mitral Annular Calcification.

BACKGROUND: Patients with mitral regurgitation (MR) and morphologic presence of relevant mitral annular calcification (MAC) represent a challenging phenotypic subset with limited treatment options. OBJECTIVES: The aim of this study was to assess the feasibility of transcatheter mitral valve replacement (TMVR) using dedicated devices for the treatment of MAC patients. METHODS: Consecutive patients with symptomatic MR receiving TMVR and with available computed tomography data from the CHOICE-MI (Choice of Optimal Transcatheter Treatment for Mitral Insufficiency) multicenter registry were stratified by the presence of none or mild mitral annular calcification (MACnone/mild) vs moderate or severe mitral annular calcification (MACmod/sev). RESULTS: Among 279 eligible patients (median age = 76.0 years [Q1-Q3: 71.0-81.0 years], EuroSCORE II = 6.2% [Q1-Q3: 3.9%-12.1%]), 222 (79.6%) presented with MACnone/mild and 57 (20.4%) with MACmod/sev. Patients with MACmod/sev had a higher prevalence of extracardiac arteriopathy (P = 0.011) and primary MR (P < 0.001). Although the technical success rate and the extent of MR elimination did not differ, TMVR treatment in MACmod/sev patients was associated with higher rates of postprocedural bleeding complications (P = 0.02) and renal failure (P < 0.001). Functional improvement at the 1- and 2-year follow-up did not differ between groups. At the 2-year follow-up, there were no differences between patients with MACmod/sev and MACnone/mild regarding all-cause mortality (38.5% vs 37.7%; P = 0.76), cardiovascular mortality (21.3% vs 24.9%; P = 0.97), and all-cause mortality or heart failure hospitalization (52.4% vs 46.7%; P = 0.28) CONCLUSIONS: TMVR in patients with MACmod/sev is associated with higher rates of postprocedural complications but similar rates of survival, MR resolution, and functional improvement compared to MACnone/mild. Further studies are necessary to define the role of dedicated TMVR devices in this population. (Choice of Optimal Transcatheter Treatment for Mitral Insufficiency Registry [CHOICE-MI]; NCT04688190).

Metastatic Calcification in Allograft Kidney Due to Persistent Secondary Hyperparathyroidism: A Rare Cause of Graft Dysfunction.

Successful kidney transplant corrects mineral and bone disorderto a large extent; however, disorders can persistin up to 80% ofrecipients.We describe a case of persistent hyperparathyroidism with graft dysfunction and metastatic calcification in graft biopsy. A 48-yearold renal transplant recipient developed graft dysfunction 3 weeks after kidney transplant. During pretransplant workup, the recipient was found to have severe secondary hyperparathyroidism (intact parathyroid hormone level of 2000 pg/mL), which was managed and well controlled before transplant. Graft dysfunction was evaluated using algorithmic approach. Prerenal causes, tacrolimus toxicity, and infections were ruled out. Graft biopsy revealed several foci of tubular and parenchyma calcific deposits (microcalcinosis) with tubular injury. The patient was restarted on medical management of hyperparathyroidism, and he showed improvement over 6 weeks, along with creatinine level returning to nadir value. Vascular and graft calcification is an independent predictor of long-term graftfunction and overall mortality. This report describes the challenges that we faced in diagnosis and management of persistent hyperparathyroidism, as no randomized controlled trials and guidelines are available.

Early arthroscopic debridement of posterior cruciate ligament calcification after symptom presentation led to immediate recovery: a case report.

BACKGROUND: We report a rare case of posterior cruciate ligament (PCL) calcification, which has only been reported in two case studies on PubMed. CASE PRESENTATION: A 71-year-old man developed left popliteal pain in the morning without any history of trauma and the pain became severe that night. On the following day, he presented to our department. The patient could not flex his left knee at all due to pain and swelling. CT and MRI scans showed calcification behind the PCL with mild osteoarthritic changes and accumulation of synovial fluid in the joint. Synovial fluid analysis did not reveal any crystals. Blood tests at first admission showed inflammation, hyperglycemia, and low blood uric acid levels. Although the patient's knee joint was injected with steroids, his symptoms did not improve. Thus, we performed arthroscopic surgery two days after symptoms had appeared. Intraoperatively, we observed a white, soft tissue in the synovial membrane behind the PCL. Part of this tissue was collected for histological analysis, which revealed sparse fibers with calcium deposits. Immediately after surgery, the patient's symptoms were completely gone. Afterward, the patient remained asymptomatic one month after surgery. CONCLUSION: This is the first reported case of debridement of PCL calcification and ossification that was performed soon after symptoms appeared. In addition, we demonstrated that early debridement led to complete recovery.

Case report: Spontaneous improvement and treatment considerations in leukoencephalopathy with calcifications and cysts.

We present the case of a patient with leukoencephalopathy with calcifications and cysts (LCC), who experienced progressive severe hemiparesis despite multiple neurosurgical interventions of a large contralateral cyst. Bevacizumab was proposed as an ultimate treatment option based on prior case reports. While awaiting reimbursement approval for bevacizumab, major improvement occurred in both clinical and radiological disease manifestations. The disease course of LCC is variable and unpredictable; neurosurgical treatment should be reserved for severe and progressive neurological deficits. Bevacizumab has been reported as a promising alternative treatment option. Importantly, in our case the observed clinical improvement would have been attributed to the effects of bevacizumab, if started when requested. Our case underscores the need for a natural history study for LCC and the necessity of validating treatment efficacy by systematic evaluation through appropriate clinical trials rather than relying on anecdotal evidence from published case reports.

Management of calcific myonecrosis using vacuum sealing drainage: A rare case report and 5-year follow-up.

 Calcific myonecrosis (CM), a rare post-traumatic sequel of the lower limb, is characterized by calcified lesions. A diagnosis of CM can be difficult owing to the longtime span from the emergence of the original trauma to the onset of the symptoms of CM. This case report aimed to feature a case of a 55-year-old gentleman who presented with a progressive painful swelling in the anterolateral aspect of the right lower leg with the initial trauma arising 11 years ago. In the conservative treatment, a fluid-filled mass was formed. The histological examination of the biopsy suggested a diagnosis of CM. The patient underwent a complete debridement operation, after which vacuum sealing drainage was used to manage the space left. Three weeks later, direct wound closure was achieved. Five-year follow-ups showed an excellent outcome without recurrence. Complete surgical debridement combined with primary closure is recommended to manage CM.

The value of perforator flap reconstruction in painful soft tissue calcifications.

Soft tissue calcifications frequently cause debilitating pain and functional impairments, considerably affecting patients' quality of life. As they are rare entities, evidence remains sparse, especially regarding treatment effectiveness and recurrence rates. While both pharmacological and surgical treatments may alleviate symptoms, complete resection is currently believed to prevent long-term recurrence of deposits. To improve understanding and raise awareness for soft tissue calcifications, the goal of this study was to review the current state of treatment and to compare benefits and possibilities of flap reconstruction versus simple excision in improving quality of life. Furthermore, we include a successful case report of complete resolution of symptoms following quadruple perforator flap reconstruction. By systematic literature review, studies published in MEDLINE between 1980 and 2024 reporting on surgical treatment and outcome of soft tissue calcifications were included, in addition to a detailed description of our case report. A total of 53 studies reporting on 197 patients with soft tissue calcifications were included. Simple surgical excision was the most commonly (85.9%) employed procedure, demonstrating a substantial recurrence rate of 13.3%. In contrast, no patients who underwent radical excision experienced recurrence. Dermal matrix grafts and flap reconstruction were successfully used in patients requiring substantial tissue coverage, highlighting their value in complex defect reconstruction following radical excision. The combination of complete surgical resection and flap reconstruction reduces recurrence rates and improves postoperative outcomes and quality of life of these patients, supporting early radical surgical intervention as the gold standard treatment for soft tissue calcifications.

[Comparison of the efficacy of phlebotomy under touch pain point and ultrasound-guided puncture decompression in the treatment of acute calcific supraspinatus tendinitis].

OBJECTIVE: To compare the efficacy of blood letting under pain point touch and ultrasound-guided puncture decompression in the treatment of acute supraspinatus muscle calcifying tendinitis. METHODS: From January 2020 to January 2023, 45 patients with acute supraspinatus muscle calcifying tendinitis were selected and divided into treatment group and control group. In the treatment group, a total of 22 patients were treated with ultrasound-guided puncture decompression, including 16 females and 6 males, aged from 20 to 64 years old(39.31±5.80) years old, 11 on the left shoulder and 11 on the right shoulder. In the control group, there were 23 cases, including 15 females and 8 males, aged from 19 to 66 years old (40.67±6.13) years old, 12 on the left shoulder and 13 on the right shoulder. The treatment was treated with pain point touch bloodletting therapy. The visual analog scale (VAS) pain score, University of California, Los Angeles(UCLA) shoulder system score and shoulder Constant-Murley score were used to evaluate the therapeutic effect before treatment, 1 weeks, 1 month and 3 months after treatment, respectively. RESULTS: One patient in the control group gave up follow-up for personal reasons after 1 week of treatment, and the other 44 patients completed all follow-up. Six months after treatment, there were no recurrence cases in both groups. After statistical analysis, VAS pain score, UCLA score and Constant-Murley score of the treatment group and the control group were significantly different from those before treatment (P<0.05), and the improvement was more obvious in the treatment group. There was no statistical significance between the two groups (P>0.05). CONCLUSION: Bloodletting under pain point touch and ultrasound-guided puncture decompression are effective in the treatment of acute calcific supraspinatus tendinitis, with simple operation and low cost, which can effectively reduce local pain and effectively improve shoulder joint function. Primary hospitals can selectively operate treatment according to their own conditions.

Updated solution for diagnosis and management of calcinosis cutis: A retrospective review.

Calcinosis cutis is classified into 5 main types: dystrophic, metastatic, idiopathic, iatrogenic, and calciphylaxis. However, it is occasionally misdiagnosed as a malignancy and its management remains challenging. Therefore, in this study, we report our diagnostic and treatment experiences with patients with calcinosis cutis and suggest strategies for improving patient care. This retrospective study included 7 patients (4 men, 3 women; 44.4 ±â€…32.0 years old) who visited our hospital between March 2013 and December 2022 and were diagnosed with calcinosis cutis through histopathological procedures. The patients underwent complete excision of the mass without a safety margin. Frozen biopsy was not performed during surgery. No significant intraoperative or postoperative complications were noted after the application of various imaging techniques for diagnosis and follow-up. All patients showed complete recovery. Follow-up showed no recurrence or complications in the 6 patients who completed 1 year of follow-up. Radiological tests such as plain radiography, ultrasonography, computed tomography, and magnetic resonance imaging are important for accurate diagnosis and treatment of calcinosis cutis. This approach can ensure precise assessment of preoperative lesions, leading to safe and less invasive patient treatment, recurrence prevention, and complications of calcinosis cutis.

Impact of pericardial calcification on early postoperative outcomes after pericardiectomy: a retrospective observational study.

BACKGROUND: Owing to the lack of understanding of the clinical significance of pericardial calcification during pericardiectomy, whether pericardial calcification should be considered when determining the optimal timing for pericardiectomy is debatable. We aimed to investigate the effect of pericardial calcification on early postoperative outcomes in patients who underwent pericardiectomy for constrictive pericarditis. METHODS: Altogether, 44 patients who underwent pericardiectomy for constrictive pericarditis were enrolled. After excluding three patients who underwent concurrent surgeries, a total of 41 patients were categorized into two groups based on the presence of pericardial calcification as determined by preoperative computed tomography and pathological examination. Preoperative clinical and imaging characteristics, intraoperative data, and early postoperative outcomes were compared between the two groups. A multivariable analysis was performed to identify the factors associated with postoperative complications. RESULTS: The group with and without PC comprised 21 and 20 patients, respectively. No significant differences were observed in 30-day mortality (n = 1 [5%]) in the group with pericardial calcification and no mortality in the group without pericardial calcification (p > 0.999). Other early postoperative outcome variables did not demonstrate any significant differences between the two groups. However, the use of cardiopulmonary bypass was associated with postoperative complications (p < 0.009, odds ratio: 63.5, 95% confidence interval: 5.13-3400). CONCLUSIONS: Pericardial calcification did not significantly affect the postoperative outcomes after pericardiectomy. Further comprehensive studies, including those with larger sample sizes and longitudinal designs, are necessary to determine whether pericardial calcification can significantly influence the timing of surgical intervention.

3D X-ray computed tomography in the analyses of intraocular lenses explanted because of postoperative opacification.

PURPOSE: To use X-ray computed tomography (CT) -which describes the acquisition and reconstruction of 2-dimensional X-ray transmission images to create a 3D representation of a specimen -in the analyses of intraocular lenses (IOLs) explanted because of optical opacification occurring postoperatively. SETTING: John A. Moran Eye Center, and Utah Nanofab, University of Utah, Salt Lake City, Utah. DESIGN: Laboratory study. METHODS: A hydrophilic acrylic and a silicone lens (the latter from an eye with asteroid hyalosis) explanted because of postoperative calcification, as well as a poly(methyl methacrylate) (PMMA) lens explanted because of snowflake degeneration underwent analysis under gross and light microscopy. Then, they were attached to an appropriate support and scanned under a Zeiss Xradia Versa X-ray microscope. After data acquisition, data segmentation was performed with a commercially available program to separate image data into components. RESULTS: Morphology, size/volume, and specific location of calcified deposits on the surface or within the substance of explanted IOLs could be demonstrated by X-ray CT within the entire volume of each lens with high contrast and resolution. The PMMA lens showed multiple spaces/fissures in relation to Nd:YAG pitting of the optic, and what appeared to be sheets of delaminated PMMA material at different levels within the optic substance. CONCLUSIONS: The key benefit of X-ray CT is that it can be performed without physically sectioning the specimen. This preliminary study demonstrates that this technology can be potentially useful in the imaging and analyses of explanted, opacified lenses.

Calcified Meningiomas Demonstrate Equivocal Grade, Proliferation, and Immediate Surgical Outcomes.

BACKGROUND/OBJECTIVE: Meningioma calcification is thought to predict reduced growth potential and aggression. However, historical studies have primarily focused on correlating calcification in small meningiomas (diameter less than 2.5 cm) rather than analyzing characteristics of calcified meningiomas across all sizes. In this study, we investigate the pathologic and clinical implications of meningioma calcification. METHODS: We utilized a historical database of 342 consecutive newly diagnosed intracranial meningiomas with preoperative computed tomography and magnetic resonance imaging scans treated at a single institution from 2005 to 2019. We correlated the presence of calcification with patient demographics, grade, Mindbomb Homolog-1 index, location, volume, Simpson grade, and recurrence using both univariate and multivariate generalized linear models. RESULTS: On univariate analysis, no single variable correlated with tumor calcification. Notably, neither tumor 2021 World Health Organization grade (P = 0.91) nor Mindbomb Homolog-1 index (P = 0.62) predicted calcification. After accounting for demographic characteristics and tumor volume and location, there was no significant association between 2021 World Health Organization grade (P = 0.52) and Mindbomb Homolog-1 index (P = 0.54) and calcification. Calcification had no influence on resection grade (P = 0.59) or recurrence (P = 0.80). CONCLUSIONS: In this series, calcified meningiomas exhibited similar 2021 World Health Organization tumor grading distribution, proliferation indexes, and immediate surgical outcomes compared to their noncalcified counterparts. These findings question the historical role of using meningioma calcification as an independent guide to their management.

Surgical Treatment of Calcified Thoracic Herniated Disc Disease via the Transthoracic Approach with the Use of Intraoperative Computed Tomography (iCT) and Microscope-Based Augmented Reality (AR).

Background and Objectives: The aim of this study is to present our experience in the surgical treatment of calcified thoracic herniated disc disease via a transthoracic approach in the lateral position with the use of intraoperative computed tomography (iCT) and augmented reality (AR). Materials and Methods: All patients who underwent surgery for calcified thoracic herniated disc via a transthoracic transpleural approach at our Department using iCT and microscope-based AR were included in the study. Results: Six consecutive patients (five female, median age 53.2 ± 6.4 years) with calcified herniated thoracic discs (two patients Th 10-11 level, two patients Th 7-8, one patient Th 9-10, one patient Th 11-12) were included in this case series. Indication for surgery included evidence of a calcified thoracic disc on magnet resonance imaging (MRI) and CT with spinal canal stenosis of >50% of diameter, intractable pain, and neurological deficits, as well as MRI-signs of myelopathy. Five patients had paraparesis and ataxia, and one patient had no deficit. All surgeries were performed in the lateral position via a transthoracic transpleural approach (Five from left side). CT for automatic registration was performed following the placement of the reference array, with a high registration accuracy. Microscope-based AR was used, with segmented structures of interest such as vertebral bodies, disc space, herniated disc, and dural sac. Mean operative time was 277.5 ± 156 min. The use of AR improved orientation in the operative field for identification, and tailored the resection of the herniated disc and the identification of the course of dural sac. A control-iCT scan confirmed the complete resection in five patients and incomplete resection of the herniated disc in one patient. In one patient, complications occurred, such as postoperative hematoma, and wound healing deficit occurred. Mean follow-up was 22.9 ± 16.5 months. Five patients improved following surgery, and one patient who had no deficits remained unchanged. Conclusions: Optimal surgical therapy in patients with calcified thoracic disc disease with compression of dural sac and myelopathy was resectioned via a transthoracic transpleural approach. The use of iCT-based registration and microscope-based AR significantly improved orientation in the operative field and facilitated safe resection of these lesions.

[Modern endoscopic technologies for chronic calcifying pancreatitis]. / Sovremennye endoskopicheskie tekhnologii pri khronicheskom kal'tsinoznom pankreatite.

OBJECTIVE: To evaluate the effectiveness and safety of electrohydraulic lithotripsy of calculi of the main pancreatic duct using ultrathin SpyGlass DS endoscope. MATERIAL AND METHODS: The study included 29 patients with chronic calcifying pancreatitis and obstructive calculi of the main pancreatic duct. All surgeries were carried out between 2018 and 2023. RESULTS: Complete removal of calculi (≥5 mm) within one procedure was achieved in 25 (86%) patients. CONCLUSION: Pancreatoscopy with electrohydraulic lithotripsy using the digital SpyGlass DS system (BostonScientificCorp, Marlborough, MA) is the most effective method for calculi of the main pancreatic duct.

Hydrodynamic Assessment of Explanted Degenerated Transcatheter Aortic Valves: Novel Insights Into Noncalcific and Calcific Mechanisms.

BACKGROUND: The etiology of transcatheter aortic valve (TAV) degeneration is poorly understood, particularly noncalcific mechanisms. OBJECTIVES: The authors sought to investigate noncalcific and calcific mechanisms of TAV degeneration and evaluate their impact on leaflet function by bench testing, imaging, and histology. METHODS: TAV explants were obtained from the EXPLANT THV registry and clinical institutions. Hydrodynamic assessment was performed using a heart valve pulse duplicator system under physiological conditions. Micro-computed tomography, high-resolution photography, high speed video, and hematoxylin and eosin staining were used to evaluate the morphological appearance, leaflet kinematics, and calcium burden of TAVs. RESULTS: A total of 14 explants were evaluated: 10 self-expanding CoreValve/Evolut TAVs (Medtronic), 3 balloon-expandable SAPIEN 3 TAVs (Edwards Lifesciences), and 1 mechanically expandable Lotus TAV (Boston Scientific). The median patient age at explantation was 73.0 years (Q1-Q3: 64.5-80.0 years), with a time to explantation of 4 years 1 month (1 year 5 months to 4 years 11 months). Six TAV explants were found to have leaflet calcification (162.4 mm3; 58.8-603.0 mm3), and 8 had no calcification detectable by micro-computed tomography and histology. All samples had impaired leaflet kinematics. There was no significant difference in the hydrodynamic mean gradient between calcified (47.2 mm Hg; 26.6-74.1 mm Hg) and noncalcified (27.6 mm Hg; 15.2-36.7 mm Hg; P = 0.28) TAVs. Leaflet calcification had a weak but nonsignificant association with the hydrodynamic mean gradient (r = 0.42; P = 0.14). CONCLUSIONS: TAV function can be severely impacted by noncalcific and calcific mechanisms of tissue degeneration. Importantly, functional stenosis can occur in TAVs in the absence of obvious and significant calcification.

Radiation Maculopathy in Patients with Malignant Melanoma of the Corpus Ciliare and Choroidea Following One-Day Session of Stereotactic Radiosurgery.

The aim of the thesis is to present the case of a patient in whom bilateral calcification of the hydrophilic intraocular lens (IOL) Lentis M+ LS-313 MF30 (Oculentis) has developed. Due to the negative effect on visual functions, explantation and replacement of the artificial lens was necessary in both eyes. Case Report: An overview of the available literature summarized the diagnostics, current examination methods and possibilities of the surgical solution of calcification of the bifocal hydrophilic lens Lentis M+ LS-313 MF30 (Oculentis). The specific solution is described in a case report of a patient in whom calcification of both lenses developed 6 years after implantation of the IOL. In 2015, the patient underwent uncomplicated cataract surgery of both eyes with the implantation of an artificial intraocular lens into the capsule. In September 2021, an 82-year-old man was examined at our outpatient clinic for deterioration of visual acuity and changes in the material of the artificial IOL which were perceptible during a clinical examination, on the recommendation of a local ophthalmologist. Blurred vision predominated. A diagnosis of intraocular lens opacification was confirmed and documented using a Scheimpflug camera (OCULUS Pentacam HR) and anterior OCT (Avanti RTVue XR Optovue,). The patient was indicated for explantation and replacement of the opacified intraocular lens in the left and subsequently in the right eye- The same type of IOL was used for reimplantation with good functional results. Conclusion: Since 2010, multifocal lens implantation has been on an upward trend worldwide. This type of MF IOL has also been used in thousands of implantations. A number of other explantations can be expected in the coming years. The optimal solution is the correct replacement of the calcified IOL with the same construction made of safer hydrophobic material.

Posterolateral approaches to the thoracic spine for calcific disc herniation: is wider exposure always better?

OBJECTIVE: To compare the costotransversectomy (CTV) and transpedicular (TP) approaches versus the transfacet (TF) approach for the surgical treatment of calcific thoracic spine herniations (cTDH), in terms of surgical and clinical outcomes. BACKGROUND: Surgical approaches for cTDH are debated. Anterior approaches are recommended, while posterolateral approaches are preferred for non-calcific, paramedian, and lateral hernias. Currently, there is limited evidence about the superiority of a more invasive surgical approach, such as CTV or TP, over TF, a relatively less invasive approach, in terms of neurological outcome, pain, and surgical complications, for the treatment of cTDH. METHODS: A retrospective, observational, monocentric study was conducted on patients who underwent posterolateral thoracic approaches for symptomatic cTDH, between 2010 and 2023, at our institute. Three groups were drafted, based on the surgical approach used: TF, TP, and CTV. All procedures were assisted by intraoperative CT scan, spinal neuronavigation, and intraoperative neuromonitoring. Analyzed factors include duration of surgery, amount of bone removal, intraoperative blood loss, CSF leak, need of instrumentation for iatrogenic instability, degree of disc herniation removal, myelopathy recovery. Afterwards, a statistical analysis was performed to investigate the bony resection of the superior posterior edge of the vertebral soma. The primary outcome was the partial or total herniation removal. RESULTS: This study consecutively enrolled 65 patients who underwent posterolateral thoracic surgery for cTDH. The TF approach taking the least, and the CTV the longest time (p < 0.01). No statistical difference was observed between the three mentioned approaches, in terms of intraoperative blood loss, dural leakage, post-resection instrumentation, total herniation removal, or myelopathy recovery. An additional somatic bony resection was successful in achieving total herniation removal (p < 0.01), and the extent of bony resection was directly proportional to the extent of hernia removal (p < 0.01). CONCLUSIONS: No statistically significant differences were highlighted between the TP, TF, and CTV regarding the extent of cTDH removal, the postoperative complications, and the neurological improvement. The described somatic bone resection achieved significant total herniation removal and was directly proportional to the preop against postop anteroposterior diameter difference.

Two cases of atrial myxoma with calcification and ossification as the main features.

BACKGROUND: Cardiac myxomas are the most common type of primary cardiac tumors in adults, but they can have variable features that make them difficult to diagnose. We report two cases of atrial myxoma with calcification or ossification, which are rare pathological subgroups of myxoma. CASE PRESENTATION: A 47-year-old woman and a 35-year-old man presented to our hospital with different symptoms. Both patients had a history of chronic diseases. Transthoracic and transesophageal echocardiography revealed a mass in the left or right atrium, respectively, with strong echogenicity and echogenic shadows. The masses were suspected to be malignant tumors with calcification or ossification. Contrast transthoracic echocardiography(cTEE) showed low blood supply within the lesions. The patients underwent surgical resection of the atrial mass, and the pathology confirmed myxoma with partial ossification or massive calcification. CONCLUSION: We report two rare cases of atrial myxoma with calcification or ossification and analyze their ultrasonographic features. Transthoracic echocardiography and cTEE can provide valuable information for the diagnosis and management of such mass. However, distinguishing calcification and ossification in myxoma from calcification in malignant tumors is challenging. More studies are needed to understand the pathogenesis and imaging characteristics of these myxoma variants.
