BACKGROUND Popliteal artery entrapment is an uncommon clinical entity that occurs due to compression of the popliteal artery by adjacent muscle and tendinous structures. Early diagnosis should be established through a combined approach of careful physical examination and history-taking, duplex ultrasonography, and CT angiography. PATIENTS AND METHODS We(More)
We present a comparative CT and MRI study of the paraspinal extramedullary hematopoiesis in 32 thalassemic patients. The patients were classified into four groups according to the MRI and CT imaging findings. Active recent extramedullary paraspinal hematopoietic masses show soft tissue behavior in both CT and MRI. Older inactive masses reveal iron(More)
Hamartomas of the spleen (splenomas) are very rare benign tumors composed of an aberrant mixture of normal splenic elements. Herein we present a unique case of a symptomatic non-palpable splenoma in a 64-year-old female patient presented with anemia and thrombocytopenia and we describe imaging findings in ultrasound, computed tomography and magnetic(More)
PURPOSE The purpose of our study was to evaluate the imaging findings of intrahepatic portosystemic venous shunts (IPSVS) in asymptomatic patients. MATERIALS AND METHODS Between 2002 and 2008, we examined 8 patients with IPSVS which were found incidentally. Diagnosis was based on ultrasonography, computed tomography and magnetic resonance imaging(More)
The perivascular spaces are normally microscopic. Even in normal brain some Robin-Virchow spaces are usually seen in the area of substantia innominata at the level of anterior commissure. Many pathologic states result in abnormal dilatation with an increased number of spaces visible on MRI imaging. Dilatation is most commonly associated with anterior(More)
Virchow-Robin spaces are enclosed spaces filled with interstitial fluid and covered with pia that accompany arteries, arterioles, veins and venules as they perforate the brain. They are round, linear or punctuate areas depending on the image that parallel cerebrospinal fluid attenuation or signal intensity. They are classically described as isointense to(More)
During the last three years, CT and MRI brain scans of 40 patients revealed falx cerebri partial ossification as an incidental finding. The patients had been admitted for brain CT and MRI for several reasons. In most cases, there was no problem in the differential diagnosis of falx cerebri ossification during interpretation of the cases. In a few cases, the(More)
