Mesenteric panniculitis is a rare condition of unknown etiology that causes inflammation of the adipose tissue in the mesentery. We describe a case in which mesenteric panniculitis was diagnosed on the basis of imaging and resolved spontaneously.
OBJECTIVE The purpose of this perspective is to describe the reliability and feasibility of methods such as direct observation of procedural skills and multisource feedback in assessment of the performance of radiology residents. CONCLUSION Workplace-based assessments such as direct observation of procedural skills have a role in the formative assessment… (More)
OBJECTIVE To determine the accuracy of FACT (focused appendiceal computed tomography) in evaluation of acute appendicitis. METHODS The study was conducted in Aga Khan University Hospital, Karachi, over a period of one year. Sixty-three patients with clinically equivocal acute appendicitis underwent thin-section non-enhanced helical CT. Axial scans were… (More)
OBJECTIVE To evaluate the role of biphasic contrast-enhanced helical CT including Hepatic Arterial Phase (HAP) imaging with Portal Venous Phase (PVP) imaging, in the detection and characterization of hepatocellular carcinomas. METHODS The study included 40 patients (M = 26, F = 14) with histopathologically proven HCC. Age range was between 30-85 years… (More)
Periosteal desmoid is a benign tumor like reactive fibrous lesion developed by repeated micro trauma. We describe the case of a 14 year old boy with pain in his right knee who underwent plain radiography followed by radionuclide bone scan. The final diagnosis was that of periosteal desmoid.
The case of a 28 years old woman presenting with headache, drowsiness and vomiting of a short duration, is presented. She was diagnosed as deep cerebral venous thrombosis on the basis of MRI findings. Treatment with heparin gave completed recovery.
OBJECTIVE To determine the role of helical C.T. scan in the diagnosis of pulmonary embolism. SETTING Radiology department, Aga Khan University Hospital. One year prospective study May 2001 to May 2002. METHODS Sixty patients suspected of having pulmonary embolism were included in this study. Helical C.T. scan chest was performed from aortic arch to lung… (More)
Pulmonary embolism was considered after sinus venosus defect repair. Upper arm injection for lung perfusion study demonstrated uptake in the brain, kidney, myocardium and spleen but not in the lungs (complete right to left shunt). A rare complication of corrective surgery for sinus venosus defect is diversion of the superior vena cava (SVC) to the left… (More)
