RESUMO

A rare case of a mid brain venous angioma with obstructive hydrocephalus is described. A dilated draining vein from the lesion in the aqueduct as the cause of the hydrocephalus is highlighted, and interesting features of the pathology of venous angiomas and associated cavernous hemangioma are described. The management of this interesting condition is discussed.

RESUMO

Vesical varices in portal hypertension are rare. We report a patient with portal hypertension who developed recurrent painless hematuria. Cystoscopy was normal. Doppler ultrasound and MR angiography showed a dilated paraumbilical vein within the falciform ligament coursing down to the urinary bladder wall and draining into the right internal iliac vein. He underwent liver transplantation for decompensated chronic liver disease. He is in good health and has not had further episodes of hematuria.

RESUMO

The efficacy of non-breath-hold magnetic resonance (MR) cholangiography at mid-field strength (0.5 Tesla) was evaluated for delineating biliary anatomy and the cause and extent of biliary obstruction. We performed 65 MR cholangiograms on a mid-field 0.5 Tesla MR unit and correlated them with contrast cholangiography and/or surgery. MR cholangiography was found to be both sensitive and specific in the detection of biliary obstruction and in the definition of its cause (sensitivity 98%, specificity 100%, positive predictive value 100%, negative predictive value 85.7%, accuracy 98%). MR cholangiography accurately predicted the level of obstruction in 94 per cent of strictures. Normal caliber intra-hepatic biliary radicles were visualised in only 6 per cent of the MR cholangiograms. In contrast, 94 per cent of dilated intrahepatic biliary radicles were demonstrated. The confluence, and right and left hepatic ducts were visualized in 98 per cent; the gall bladder in 65 per cent; the cystic duct in 45 per cent and the cystic duct insertion in 25 per cent. The extrahepatic bile duct was seen in 82.7 per cent. A normal caliber pancreatic duct was seen in 18 per cent while a dilated pancreatic duct was seen in 86 per cent. The pancreatico-biliary junction was visualised in 7 per cent. Non-breath-hold MR cholangiography at midfield strength is a highly accurate method of evaluating the cause and level of biliary obstruction, comparable to high-field MR cholangiography. The spatial resolution however is inadequate for the detection of variations in biliary or pancreatic ductal anatomy when the ducts are of normal caliber.

RESUMO

We report the findings on CT and MR imaging in a patient with rapidly progressive subacute sclerosing panencephalitis (SSPE), which correlated with the clinical progression of the disease. In view of the rapid neurological deterioration and CSF pleocytosis, a brain biopsy was done and this confirmed the diagnosis.
