IGG4-related giant lymphoproliferative-inflammatory left atrial mass.

Cardiac masses are rare entities that can be challenging in clinical diagnosis and management. Cardiac masses can be detected incidentally in patients with an asymptomatic course or may cause systemic inflammation findings due to inflammatory cytokine release or symptoms such as shortness of breath, chest pain, syncope, sudden cardiac death, and mortality due to the location of the mass. Cardiac masses associated with systemic inflammatory disorders are uncommon in this disease group. This case report will present a case with an asymptomatic IgG4-related left atrial mass detected in routine echocardiographic control imaging due to rheumatic valve disease.

Promising Outcome of Radiation Therapy for Chondroblastoma of Temporal Bone in Childhood: A Case Report.

Chondroblastoma is a rare cartilaginous benign bone tumor. Chondroblastoma in the temporal bone is also quite rare. Total excision is the main treatment. Data regarding tumor response to radiation therapy (RT) is insufficient. We describe a case of chondroblastoma that was treated with RT following subtotal tumor resection. In this case, the patient was a 14-year-old male who presented with a three-month history of ear fullness and hearing loss in his right ear. Magnetic resonance imaging revealed a mass partly filling the right external auditory canal and the inferior part of the middle ear. Histopathological findings indicated chondroblastoma. Subtotal tumor resection was performed due to risk of complications. RT was planned upon the growth of the tumor during follow-up. Treatment with subtotal resection and postoperative RT has been successful and the patient had no recurrence in the course of the 12-year follow-up. In chondroblastoma, complete surgical resection is still the gold standard. But the success of subtotal resection followed by adjuvant RT should also be kept in mind for cases where the total excision would pose high morbidity.

The Effectiveness of Prostate Imaging and Reporting and Data System Version 2 in the Diagnosis of Prostate Cancer with Screening Parameters Correlation.

PURPOSE: Prostate cancer is the most commonly diagnosed cancer and the second most common reason for cancer-related mortality in men. The purpose of cancer screening is to detect the disease at an early stage to help effective treatment. This study aimed to investigate the effectiveness of MRI and PI-RADS in the diagnosis of prostate cancer and examine the relation between screening parameters with prostate cancer. METHODS: The PACS system was analyzed and MRI images between September 2016 and April 2018 were listed. The state of patients regarding having pathology results were obtained. PSA values were listed. The prostate volume and the prostate density was calculated. PI-RADS assessment was used for each prostate lesion. RESULTS: Data of 138 patients were included in the study. The mean age was 63±8.9. The mean prostate gland volume was 63.8±39.3ml, the mean PSA value was 12.51±25.22 and the mean PSA density was calculated as 0.319±0.945. A statistically significant difference was found between age and prostate volume and cancer. The age of the cancer cases was higher than those who did not have cancer (p<0.05). A negative correlation was found between prostate volume and cancer status. The prostate volume of non-cancer cases was higher compared to cancer cases (p=0.0001). 55 patients had no malignancy. It was observed that 56.4% of cancer patients had significant cancer. The frequency of using PI-RADS scores was 4% for P1, 36% for P2, 14% for P3, 28% for P4, and 18% for P5. Clinically significant cancer was present in 57.9% of patients with PI-RADS score4 and 69.6% of patients with PI-RADS score5. It was found that diagnostic values were significantly high for prostate cancer screening in patients with PI-RADS scores4 and 5 (Sensitivity 76.4%, Specificity 73.5%, Negative predictive value 82.4%, Positive predictive value 65.6%). CONCLUSION: PI-RADS and MRI can be useful for the diagnosis of the clinically significant prostate cancer in patients at risk for prostate cancer. It is a non-invasive, repeatable method for prostate cancer screening and diagnosis. In prostate screening PSA reliability may be questioned. Additional methods are needed for the diagnosis. For this reason MRI and PI-RADSv2 is an effective predictor of prostate cancer in patients with high PSA levels.

Correlation of Morphological and Functional Cardiac Images: Fusion of Myocardial Perfusion SPECT and CT Angiography.

Objectives: The current study evaluates the value of cardiac hybrid imaging (CHI), performed by the fusion of functional and anatomic cardiac images, in the detection of hemodynamically significant coronary stenosis in cases with multiple coronary stenosis. Methods: A total of 36 patients (10 female, 26 male) in whom ischemia or infarction was detected on gated myocardial perfusion single photon emission computed tomography (gMPS) and multiple coronary stenosis were concomitantly detected on coronary computed tomography angiography (CCTA) and undergone invasive coronary angiography (ICA) was included in this study. Statistical analyses were performed using SPSS 22 Windows software. McNemar test was applied to show concordance between coronary CT angiography, ICA and CHI in the detection of anatomically or hemodynamically significant stenosis in three major coronary arteries. Comparison results of coronary arteries responsible for perfusion defects on CHI and gMPS are presented as percentages (%). Results: There was total accordance between coronary arteries leading to perfusion defects detected by gMPS and CHI in 50% of patients. It was observed a partial accordance in 36.1% of the patients. Additionally, it was also detected perfusion defects originated from side branches in 25% of the patients. Between results of CCTA and ICA, no statistically significant difference was noted in the detection of anatomically significant stenoses in the left main coronary artery, left anterior descending artery (LAD), left circumflex artery (LCx) and right coronary artery (RCA) (p=1.000, 0.070, 0.549, and 1.000, respectively). In addition, no statistically significant difference was found in the detection of anatomically and hemodynamically significant stenoses in LAD, LCx and RCA by CCTA and CHI (p=0.344, 0.629, and 0.219, respectively). No statistically significant difference was observed in the detection of anatomically and hemodynamically significant stenoses in LAD, LCx and RCA by ICA and CHI (p=0.804, 1.000, and 0.344, respectively). Conclusion: It is possible to detect hemodynamically significant coronary stenosis directly by CHI modality in patients with multiple coronary stenosis, wide perfusion defects.

Ocular Complications of Intravesicular BCG Treatment for Bladder Carcinoma.

PURPOSE: To report genital and ocular Bacillus Calmette-Guérin (BCG) infection as a rare complication of intravesical BCG immunotherapy. METHODS: We report a patient with bladder carcinoma who developed penile and ocular BCG infection. Medical history, clinical features, imaging findings, histopathological evaluation, and response to treatment clinched the diagnosis. RESULT: Granulomatous inflammation was noted on histopathological evaluation of lung and cutaneous lesion of the penis. The left eye with choroidal tubercle and tractional retinal detachment involving fovea underwent pars plana vitrectomy. After silicone removal, best-corrected visual acuity was 20/100 and patient received anti-TB regimen for 12 months. At 1 year follow-up, the choroidal tuberculoma was found to have completely resolved and the ocular status was stable. CONCLUSIONS: Though there are other reported cases of BCG infection secondary to intravesical BCG instillation noted in the literature, penile granuloma accompanying with choroidal tubercle is an uncommon form among these complications.

Relationship between chest computed tomography findings and clinical conditions of coronavirus disease (COVID-19): A multicentre experience.

AIMS: This study aimed to investigate the clinical and chest computed tomography (CT) features associated with clinical parameters for coronavirus disease (COVID-19) in the capital of Turkey, Ankara. MATERIALS AND METHODS: Epidemiological, clinical features, laboratory findings and radiological characteristics of 1563 hospitalised patients with COVID-19 in Ankara were collected, reviewed and analysed in this study. The risk factors associated with disease severity were investigated. RESULTS: Non-severe (1214; 77.7%) and severe cases (349; 22.3%) were enrolled in the study. Compared with the non-severe group, the severe group were significantly older and had more comorbidities (ie, hypertension, diabetes mellitus, cardiovascular disease and chronic kidney disease). Smoking was more common in the severe group. Severe patients had higher respiratory rates and higher incidences of cough and dyspnoea compared with non-severe patients. Compared with the non-severe patients, the severe patients had increased C-reactive protein (CRP), procalcitonin, neutrophil to lymphocyte ratio (NLR) and CRP/albumin ratio and decreased albumin. The occurrence rates of consolidation, subpleural sparing, crazy-paving pattern, cavity, halo sign, reversed halo sign, air bronchogram, pleural thickening, micronodule, subpleural curvilinear line and multilobar and bilateral involvement in the CT finding of the severe patients were significantly higher than those of the non-severe patients. CONCLUSIONS: Many factors are related to the severity of COVID-19, which can help clinicians judge the severity of the patient and evaluate the prognosis. This cohort study revealed that male sex, age (≥55 years), patients with any comorbidities, especially those with cardiovascular disease, dyspnoea, increased CRP, D-dimer and NLR, and decreased lymphocyte count and CT findings of consolidation and multilobar involvement were predictors of severe COVID-19.

Determining the Thyroid Gland Volume Causing Tracheal Compression: A Semiautomated 3D CT Volumetry Study.

Background and objectives: Increased thyroid gland volume (TV) may bring about tracheal compression, which is one of the causes of respiratory distress. The aim of this study was to investigate the relationship between TV and the severity of tracheal compression independent of patients' symptoms using semiautomated three-dimensional (3D) volumetry (S3DV) reconstructed from computed tomography (CT) scans. Cut-off TVs leading to different levels of tracheal narrowing were evaluated. Materials and Methods: One hundred sixty-three contrast-enhanced head and neck CT examinations were retrospectively assessed. TVs were measured by S3DV. The degree of tracheal compression was measured at the point where the greatest percent reduction in the cross-sectional area of the trachea adjacent to the thyroid gland was observed. To determine the severity of compression, the tracheal compression ratio (TCR) was defined (TCR = A1 (the narrowest cross-sectional area of trachea)/A2 (the largest cross-sectional area of trachea)). Results: The mean tracheal narrowing was 15% (TCR = 0.85 ± 0.15) in the study population. Patients with more than 15% tracheal compression had significantly higher TV values than those with less than 15% tracheal compression (p < 0.001). In addition, a significant correlation was found between TV and tracheal compression (p < 0.001). Moreover, the receiver operating characteristic (ROC) curve analysis revealed that the cut-off levels for TV that predict a tracheal narrowing of 10%, 20%, 30%, and 40% were 19.75 mL, 21.56 mL, 24.54 mL, and 30.29 mL, respectively (p < 0.05). Conclusions: This study objectively demonstrated that larger thyroid glands cause more severe compression on the trachea. The results may be helpful during the decision-making process for thyroidectomies to be performed due to compression symptoms.

Imaging Findings of Jugular Foramen Meningocele in a Neurofibromatosis Type 1 Patient.

Neurofibromatosis type I (NF1) is a neurocutaneous disorder that involves autosomal dominant transmission. Skull defects, including sphenoid dysplasia and calvarial defects, are a rare finding in patients with NF1. Spinal meningocele and sphenoid wing dysplasia have been identified in NF1 but the occurrence of meningoceles at the skull base is extremely rare. A rare instance of jugular foramen meningocele being identified in an NF1 patient on imaging is described in this paper. To the best of our knowledge, only two such cases have been reported in the English literature.

Non-coronary abnormalities of the left heart: CT angiography findings.

Cardiac computed tomography (CT) is most commonly performed for the evaluation of the coronary arteries; however, non-coronary cardiac pathologies are frequently detected on these scans. In cases where magnetic resonance imaging cannot be used, cardiac CT can serve as the first-line imaging modality to evaluate many non-coronary cardiac pathologies. In this article, we discuss congenital non-coronary abnormalities of the left heart and their cardiac CT imaging features.

Late embolization of the atrial septal occluder device into the abdominal aorta.

Although early device embolization is a well-known complication of percutaneous atrial septal defect (ASD) closure, late device embolization is rarely encountered and information about management of it are very limited. Herein, we reported a case of late ASD device embolization into the abdominal aorta at the level of the superior mesenteric artery, 8 months after percutaneous closure.
