Histopathologic Analysis

Leiomyomas of the kidney are rare, mostly occurring in adults as incidental findings, and are a diagnostic challenge. In a renal transplant recipient population, an increased risk of tumors is observed due to the effect of immunosuppressive drugs. A differential diagnosis between leiomyomas and other malignant lesions is not possible with current imaging methods. This report presents a case of a native kidney capsular leiomyoma in a kidney transplant recipient and highlights the features of computed tomography and contrast-enhanced ultrasound (CEUS), along with the histopathologic analysis. The CEUS and quantification studies are helpful in demonstrating the vascularization pattern of the renal capsular leiomyoma. This entity appearing with chronic kidney disease can resemble a renal cell carcinoma, in an otherwise healthy kidney. In this case, CEUS was useful for diagnosing the vascularization of the renal mass, although the pattern of intense vascularization could be diagnostically misleading, implying a malignant lesion. However, the pattern of enhancement due to CEUS showed no peculiarities that indicated histopathologic diagnosis.

Tension Gastrothorax

Tension gastrothorax is a rare, life-threatening clinical condition caused by intrathoracic herniation of the stomach through a diaphragmatic defect which becomes increasingly distended over time. If not recognized promptly, this can rapidly progress to respiratory distress, mediastinal shift, and hemodynamic compromise. Initial clinical presentation and imaging findings closely mirror those of tension pneumothorax, confounding diagnosis and potentially leading to unnecessary interventions with increased risk of morbidity and mortality. Here, we present a case of an elderly female who presented with a non-traumatic tension gastrothorax and a review of key imaging features and strategies to aid in recognition and accurate diagnosis of this emergent clinical entity.

Introduction: About 20% of TIAs are due to large vessel disease. Carotid stenosis >50% which is causing a TIA or stroke needs to be definitely managed quickly in order to benefit. Alternatively, dual antiplatelet therapy may be considered. The objective of this study was to determine high-risk diagnostic findings associated with symptomatic carotid disease in ED patients with TIA to indicate patients requiring urgent carotid imaging. Methods: We performed a prospective Canadian multicenter cohort study, at 13 academic sites, of ED patients with TIA or non-disabling stroke from 2006-2014. Study research nurses recorded imaging findings on standardized data collection forms from the final reports of all imaging tests ordered in the ED on prospectively enrolled patients by treating emergency physicians. Symptomatic carotid disease was defined as carotid stenosis 50-99% or carotid dissection and was adjudicated by stroke neurology to be the etiology of the index event. Patients were followed by medical review and telephone up to 90 days. Univariate analysis was conducted for investigation results with our primary outcome. Results: The cohort included 305 patients with and 5,277 without symptomatic carotid disease. Positive predictors of symptomatic carotid disease included platelet count over 400 x 109/L (15.3% vs 7.6%; p=0.0095), blood glucose >15 mmol/L (11.4% vs 4.4%; p<0.0001), CT evidence of acute infarction (9.8% vs 4.1%; p<0.0001), CT evidence of old infarction (35.7% vs 24.1%; p<0.0001), and CT evidence of any infarct (43.3% vs 26.7%; p<0.0001). There were no negative predictors of symptomatic carotid disease. Conclusion: High-risk investigation findings suggestive of symptomatic carotid disease in ED TIA patients include platelet count over 400 x 109/L, blood glucose >15 mmol/L, CT evidence of any infarction. Patients with any of these findings should be considered for rapid carotid imaging.

BackgroundLate onset depression (LOD) may precede the diagnosis of Parkinson’s disease (PD) or dementia with Lewy bodies (DLB). We aimed to determine the rate of clinical and imaging features associated with prodromal PD/DLB in patients with LOD.MethodsIn a cross-sectional design, 36 patients with first onset of a depressive disorder (Diagnostic and Statistical Manual of Mental Disorders IV criteria) diagnosed after the age of 55 (LOD group) and 30 healthy controls (HC) underwent a detailed clinical assessment. In addition, 28/36 patients with LOD and 20/30 HC underwent a head MRI and 29/36 and 25/30, respectively, had dopamine transporter imaging by 123I-ioflupane single-photon emission computed tomography (SPECT) imaging. Image analysis of both scans was performed by a rater blind to the participant group. Results of clinical assessments and imaging results were compared between the two groups.ResultsPatients with LOD (n=36) had significantly worse scores than HC (n=30) on the PD screening questionnaire (mean (SD) 1.8 (1.9) vs 0.8 (1.2); p=0.01), Movement Disorder Society Unified Parkinson’s Disease Rating Scale total (mean (SD) 19.2 (12.7) vs 6.1 (5.7); p<0.001), REM-sleep behaviour disorder screening questionnaire (mean (SD) 4.3 (3.2) vs 2.1 (2.1); p=0.001), Lille Apathy Rating Scale (mean (SD) −23.3 (9.6) vs −27.0 (4.7); p=0.04) and the Scales for Outcomes in PD-Autonomic (mean (SD) 14.9 (8.7) vs 7.7 (4.9); p<0.001). Twenty-four per cent of patients with LOD versus 4% HC had an abnormal 123I-ioflupane SPECT scan (p=0.04).ConclusionsLOD is associated with increased rates of motor and non-motor features of PD/DLB and of abnormal 123I-ioflupane SPECTs. These results suggest that patients with LOD should be considered at increased risk of PD/DLB.

The aim was to investigate the frequency and spectrum of cardiac involvement (CI) in patients with Behçet syndrome (BS) in the Tunisian context, and to assess the clinical and imaging features, treatment, and outcomes. We retrospectively retrieved the medical records of patients with CI among 220 BS patients admitted to the hospital internal medicine department between February 2006 and April 2019, who fulfilled the International Study Group diagnostic criteria for BS. Ten patients (8 men, 2 women) were eligible for the study. Mean age was 37.3 years. Three patients had 2 isolated episodes of cardiac BS. The different types of CI were coronary artery disease (5/10), intracardiac thrombus (4/10), pericarditis (1/10), myocarditis (1/10), and myocardial fibrosis (1/10). Five patients had associated vascular involvement (50%). Medical treatment was based on corticosteroids and colchicine in all patients (100%), anticoagulants in 8 (80%), and cyclophosphamide followed by azathioprine in 9 (90%). The clinical course was favorable in 9 patients; 1 patient died. CI remains an important feature of BS because of its association with increased risk of mortality and morbidity. Therefore, early screening and detection with imaging methods are paramount. Also, better cooperation between rheumatologists and cardiologists could improve outcomes.

Aim: To investigate clinical, laboratory and imaging features of COVID-19 patients in Bushehr, a southern province of Iran. Materials & methods: A total of 148 COVID-19 patients were enrolled. The patients were categorized into four groups including inpatients, outpatients, elderly and nonelderly. Clinical, laboratory and computed tomography characteristics were analyzed and compared. Results: Levels of erythrocyte sedimentation rate, CRP, lactate dehydrogenase and aspartate aminotransferas among inpatients were higher than outpatients. There were significant differences in the levels of creatinine and blood urine nitrogen between elderly and nonelderly patients. The incidence of ground-glass opacities in inpatients was significantly higher than in outpatients. Conclusion: COVID-19 is associated with more severe renal failure in elderly patients. Elderly patients with underlying conditions are at increased risk of severe progression of COVID-19.
