RESUMO

OBJECTIVE: The aim of this study was to investigate the relationship between left-sided varicocele and epididymitis or epididymo-orchitis. MATERIALS AND METHODS: The study included 72 patients with left side epididymitis (EP) or epididymo-orchitis (EPO) (Group 1) and a control group of 72 patients without EP or EPO (Group 2). Those with right EP-EPO were excluded due to possible other underlying retroperitoneal pathologies causing varicocele. Groups were evaluated for presence of left side varicocele, varicocele grade and pampiniform plexus vein diameter. RESULTS: The average age was 38 ± 8.4 years (range, 18-50 years) in Group 1, and 36 ± 9.1 years (range, 16-47 years) in Group 2. Varicocele was significantly more common in patients with EP or EPO (p < .001). The rate of varicocele was 66.7% (48/72) in Group 1, and 22.3% (16/72) in Group 2. The median grade of varicocele was 2 in Group 1, and 0 in Group 2. Pampiniform plexus vein diameters were found to be significantly larger in patients with EP or EPO compare to patients without EP and EPO. The median vein diameter was 3.3 mm with the 25th and 75th percentiles at 2.7 and 3.8 mm, and was 1.9 mm with the 25th and 75th percentiles at 1.7 and 2.3 mm, respectively (p < .001). CONCLUSIONS: Left-sided varicocele was significantly more common in patients with EP or EPO and it is an important cause for the development of EP/EPO because of chronic venous stasis.

RESUMO

BACKGROUND: Some pathologies associated with abnormal patellar height have been reported in the literature. However, its relationship with some pathologies, such as anterior cruciate ligament mucoid degeneration (ACL-MD) and focal cartilage defect, has not been investigated. PURPOSE: To investigate the relationship between patellar height with patellar-quadriceps tendinopathy, quadriceps fat pad edema, ACL-MD, and focal cartilage defect. MATERIAL AND METHODS: Magnetic resonance imaging of the knees of 261 patients were classified into three groups as normal, patella alta, and patella baja, and evaluated in terms of patellar-quadriceps tendinopathy, quadriceps fat pad edema, ACL-MD, and focal cartilage defect. RESULTS: There were 261 patients (140 men, 121 women; age range = 18-60 years; mean age = 30 ± 4.7 years). Of the 261 patients, 181 (69.3%) were normal, 56 (21.4%) were patella alta, and 24 were patella baja (9.1%). Patellar-quadriceps tendinopathy, quadriceps fat pad edema, and ACL-MD rates were significantly higher compared to the normal group (P <0.05). While a moderate positive correlation was found between patellar height shift and patellar-quadriceps tendinopathy and ACL-MD, there was a small correlation between patellar height shift and quadriceps fat pad edema. The rate of focal cartilage defect was significantly higher in the middle part of the lateral femoral condyle and lateral knee joint only in patella alta. CONCLUSION: The risk of patellar-quadriceps tendinopathy, quadriceps fat pad edema, ACL-MD, and lateral focal cartilage defect is higher in patients with alta-baja. The radiologist should evaluate these pathologies more carefully, especially subtle ones, in patients with abnormal patellar height.

RESUMO

BACKGROUND: This prospective study assesses the use of rapid remote online cytological evaluation for diagnosing endoscopical achieved biopsies. It focuses on its effectiveness in identifying benign and malignant conditions using digital image processing. METHODS: The study was conducted between April 2021 and September 2022 and involved analyses of 314 Rapid Remote Online Cytological Evaluations in total (154 imprint cytologies, 143 fine needle aspirations and 17 brush cytologies) performed on 239 patients at the LungenClinic Grosshansdorf. During on-site evaluation via telecytology, the time requirement was recorded and the findings were compared with the cyto-/histological and final diagnoses. RESULTS: By means of rapid remote online evaluation, findings of 86 cytological benign, 190 malignant and 38 unclear diagnoses were recorded (Ø assessment time, 100 s; range, 11-370 s). In 27 of the 37 specimens with unclear diagnoses, the final findings were malignant tumours and only 6 were benign changes. The diagnosis of another 4 of these 37 findings remained unclear. Excluding these 37 specimens, rapid remote online evaluation achieved a sensitivity of 90.5% with a specificity of 98.5% and a correct classification rate of 92.4% with regard to the final diagnosis of all cases. As expected, an increase in the sensitivity rate for the cytological detection of malignant tumours (76.1% vs. 92.5%) was found especially in fine-needle aspirations. CONCLUSIONS: Rapid remote online analysis allows the fast quantitative and qualitative evaluation of clinically obtained cytological specimens. With a correct classification rate of more than 93%, sampling deficiencies can be corrected promptly and diagnostic and therapeutic approaches can be derived.

RESUMO

STUDY OBJECTIVE: To assess to what degree can digestive symptoms improve after endometriosis surgery for different localizations. DESIGN: A comparative retrospective study employing data prospectively recorded in the North-West Inter-Regional Female Cohort for Patients with Endometriosis (CIRENDO) from June 2009 to November 2018. SETTING: Two referral centers. PATIENTS: A total of 1497 women undergoing surgery because of pelvic endometriosis were divided into 3 groups: superficial endometriosis (Group 1, n = 396), deep endometriosis sparing the bowel (Group 2, n = 337), and deep endometriosis involving the bowel (Group 3, n = 764). INTERVENTIONS: Surgery for endometriosis. MEASUREMENTS AND MAIN RESULTS: Preoperative and postoperative gastrointestinal symptoms were evaluated with standardized questionnaires, including the Gastrointestinal Quality of Life Index (GIQLI) and Knowles-Eccersley-Scott-Symptom questionnaire (KESS). The degree of postoperative improvement in digestive symptoms was compared between the groups. The women in Group 3 were significantly symptomatic in terms of cycle-related gastrointestinal symptoms and scores of standardized questionnaires GIQLI and KESS. According to the 1-year postoperative evaluation, women in Group 3 experienced the most significant improvement in their gastrointestinal symptoms. CONCLUSION: Women with severe bowel symptoms and deep endometriosis infiltrating the bowel should be informed about the high probability of symptom improvement after the removal of bowel nodules. Conversely, in women without deep endometriosis, postoperatively, there is less improvement in baseline digestive complaints.

RESUMO

BACKGROUND: Gallium 68-tetraazacyclododecane-tetraacetic acid-octreotate ([68Ga]Ga-DOTA-TATE) is a selective somatostatin analogue ligand, which shows increased affinity for somatostatin receptor subtype (SSTR) 2 and has been used routinely for imaging neuroendocrine tumors with PET/CT. We investigated the utility of [68Ga]Ga-DOTA-TATE positron emission tomography/computed tomography (PET/CT) in patients with suspected pituitary pathology. We reviewed imaging for twenty consecutive patients (8 men, 12 women, mean age of 48.2, range 14-78) with suspected pituitary pathology who were referred for [68Ga]Ga-DOTA-TATE PET/CT. RESULTS: Nine patients presented with recurrent Cushing's syndrome following surgical resection of pituitary adenomas due to recurrent Cushing's disease (seven patients) and ectopic ACTH secreting tumor (2 patients). All seven patients with recurrent Cushing's disease showed positive pituitary [68Ga]Ga-DOTA-TATE uptake while both cases of ectopic hormonal secretion had absented pituitary uptake. In 1 of these 2 patients, [68Ga]Ga-DOTA-TATE was able to localize the source of ectopic ACTH tumor. Six patients presented de novo with Cushing's due to ectopic ACTH secretion; [68Ga]Ga-DOTA-TATE PET/CT was able to localize ectopic tumors in six of eight patients (3 lungs, 2 pancreases, 1 mid-gut) There was high uptake [68Ga]Ga-DOTA-TATE in 3 cases of recurrent central hyperthyroidism (SUVmax 6.6-14.3) and 2 cases of prolactinoma (SUVmax 5.5 and 11.3). CONCLUSION: Absent [68Ga]Ga-DOTA-TATE activity in the pituitary fossa is useful in excluding pituitary disease in recurrent Cushing's. Recurrent pituitary thyrotropinomas and prolactinomas showed moderate to high pituitary activity. In addition, in Cushing's syndrome, [68Ga]Ga-DOTA-TATE is useful for detection of ectopic sources of ACTH production, especially where anatomic imaging is negative.

RESUMO

PURPOSE: To determine the utility of F-fluoro-L-3,4-dihydroxy-phenylalanine (F-DOPA) PET/MRI versus cross-sectional MRI alone in glioma response assessment and identify whether the two techniques demonstrate different tumour features. METHODS: F-DOPA PET/MRI studies from 40 patients were analysed. Quantitative PET parameters and conventional MRI features were recorded. Tumour volume was assessed on both PET and MRI. Using dynamic susceptibility contrast perfusion-weighted imaging, maps of cerebral blood flow (CBF) and cerebral blood volume (CBV) were obtained. Within volume of tumours of tumour features and normal-appearing white matter (NAWM) drawn on MRI, standardised uptake value (SUV)max, CBF and CBV were recorded. Presence of residual active tumour was assessed by qualitative visual assessment. Receiver operating characteristic analysis was performed univariately and on parameter combination to analyse ability to determine presence/absence of disease. Reference standard for presence of viable tissue was biopsy or clinical follow-up. RESULTS: Median SUVmax was 3.4 for low-grade glioma (LGG) and 3.3 for high-grade glioma (HGG). There was a significant correlation between PWI parameters and WHO grade (P < 0.001), but no correlation with SUVmax. Median F-DOPA volume was 8216.88 mm for HGG and 6284.94 mm for LGG; MRI volume was 6316.57 mm and 5931.55 mm, respectively. SUVmax analysis distinguished enhancing and nonenhancing components from necrosis and NAWM and demonstrated active disease in nonenhancing regions. Visually, the modalities were concordant in 37 patients. Combining the multiparametric PET/MRI approach with all available data-enhanced detection of the presence of tumour (area under the curve 0.99, P < 0.01). CONCLUSION: MRI and F-DOPA are complementary modalities for assessment of tumour burden. Matching F-DOPA and MRI in assessing residual tumour volume may better delineate the radiotherapy target volume.

RESUMO

A 54-year-old man with multiple endocrine neoplasia type 1 had previous history of parathyroid surgery and left thyroid lobectomy 5 years earlier, and was referred for recurrent hypoglycemic episodes. Ga-DOTATATE PET/CT had showed multiple lesions in the right lung, liver, and pancreas. Biopsy from pancreas revealed low-grade neuroendocrine neoplasia. After 2 fractions of Lu-DOTATATE therapy, the size of lesions and its activity reduced on the Ga-DOTATATE scan and the hypoglycemic episodes manifested every day have scaled down to 1 time over 1-year follow-up. Herein, we report a case of malignant insulinoma successfully treated with radiolabeled somatostatin receptor therapy using Lu-DOTATATE.

RESUMO

PURPOSE: To search for CSF dynamics of idiopathic intracranial hypertension (IIH) and communicating hydrocephalus and any correlation between MRI findings, CSF metrics and CSF opening pressure in IIH. MATERIALS AND METHODS: Healthy subjects (30) and subjects with IIH (29) and high-pressure communicating hydrocephalus (43) were enrolled. Nonparametric Kruskal-Wallis test (p = 0.05) was used to compare three groups, Mann-Whitney U test with Bonferroni correction to compare two groups (p = 0.016). Correlation of MRI findings of IIH with CSF metrics and CSF opening pressure was analyzed by Spearman's Rank correlation coefficient (p = 0.05). RESULTS: In IIH, no correlation between MRI findings and aqueductal stroke volume (ASV) but statistically significantly CSF opening pressure in the presence of transverse sinus compression was noted. Comparing with healthy subjects, ASV was nonsignificantly lower and standardized diastolic and sum and difference of systolic and diastolic flow durations were statistically significantly lower. Comparing with hydrocephalus, the width of prepontine cistern (PPC)/the width of aqueductus sylvii (AS) was significantly higher and other CSF metrics with standardized systolic and sum of systolic and diastolic flow durations were significantly lower. In hydrocephalus, ASV and peak velocities were significantly higher. Compared with normal group, PPC/AS and reverse/forward flow duration were significantly lower and other CSF metrics were significantly higher. CONCLUSION: In hydrocephalus, significant increase in ASV and peak velocities were noted. In IIH, CSF opening pressure was statistically significantly high in the presence of transverse sinus compression and standardized diastolic flow durations were statistically significantly short that are probably effects of increased impedance of CSF flow against increased intracranial pressure and unchanged or even decreased intraventricular CSF volume.

RESUMO

Adult intussusception is a rare clinical condition. In majority of adult cases, there is an underlying cause such as polyps or colon cancers. In the present study, a 29-year-old woman with intermittent and colicky abdominal pain, constipation, and painful defecation, accompanied with distention and sense of rectal fullness, was evaluated with computed tomography. Ileo-colo-colic intussusception was determined. Subtotal colectomy with posterior rectopexy was performed. After the surgery, she was doing well at 13-month follow-up.

RESUMO

PURPOSE: This study aimed to define hyperperfusion in carotid stenting patients without excluding patients with stenosis on the contralateral side. MATERIALS AND METHODS: A total of 32 patients were enrolled. Prestent computed tomography perfusions were performed within 1 week before stenting, poststent perfusions 3 days after stenting. Prestent relative cerebral blood volume, relative cerebral blood flow, and relative mean transient time (rMTT) were calculated by dividing measurements from ipsilateral stent sides to contralateral sides and prestent difference mean transit time (dMTT) by subtracting contralateral mean transient time (MTT) from ipsilateral MTT. Poststent values were calculated similarly. For differences between prestent and poststent values, independent t test was used between groups and paired sample t test within the groups. RESULTS: Of the 31 patients, 4 showed poststent clinical hyperperfusion syndrome. Six showed poststent radiologic hyperperfusion with increased cerebral blood flow, increased or spared cerebral blood volume, and shortened MTT values, but only 1 demonstrated clinical hyperperfusion. Between normal and hyperperfused groups, only appreciable difference was noted in prestent and poststent dMTT without statistical significance. Within the groups, only statistical difference (P < 0.001) was noted in rMTT and dMTT in normal groups and no significant difference in the hyperperfused group. CONCLUSIONS: Radiologic hyperperfusion does not match clinical hyperperfusion. Normal group responded to stenting with statistically significant changes of rMTT and dMTT. Hyperperfusion mostly occurred in the contralateral critically stenosed patients. The hyperperfused group, due to similar MTT of both hemispheres and ipsilateral internal carotid artery being the main feeder of both hemispheres, did not show significant changes in their rMTT and dMTT values after stenting. This shows that reduced hemodynamic reserve is the main reason behind the hyperperfusion after carotid stenting.

RESUMO

Internal jugular vein thrombosis (IJVT) is a rare condition associated with malignancy, coagulopathy, and trauma. The optimal management of any IJVT must be individualized and depends on the condition of the patient. Case Presentation. We report the case of a 42-year-old woman with a history of a first trimester spontaneous abortion. Apart from a tension-type headache, she had no neurological symptoms. She reported an incidental diagnosis of right-sided IJVT when she was evaluated for hyperthyroidism ultrasonographically. On ultrasonography, we observed bilateral jugular vein thrombosis. The patient was started on oral warfarin. Seven months later, when she was adequately anticoagulated, she developed a second thrombosis. According to the etiological workup, she had a mutation in the homozygous methylene tetrahydrofolate reductase (MTHFR) gene and reduced protein C levels and activity. Conclusion. This report illustrates an unusual presentation of a rare condition. In this case, the etiology was associated with the coagulopathy, which occurred despite adequate anticoagulation.

RESUMO

During the follow-up of recurrent pneumonia in a 9-month-old girl, rhinorrhea with discharge of a positional and intermittent nature was discovered. Radiological assessment was requested to detect any skull base openings and cerebrospinal fluid (CSF) leakage. T2-weighted MR cisternography showed bilateral inner ear dysplasia, communication of the internal auditory canal with the vestibule, and effusion in the right middle ear. Intrathecal contrast-enhanced MR cisternography revealed a CSF fistula from the right internal auditory canal to the Eustachian tube. The patient was operated upon on the right side, and the presence of a CSF leak near the oval window was confirmed. No adverse effects were seen during the short-term and long-term follow-up. Diagnosing this case required special attention, careful examination, and relevant investigations to find the site of CSF leakage in this patient with bilateral inner ear dysplasia.
