Two cases of venous aneurysm of the intrahepatic portal vein branch: MR demonstration.

Two cases are reported of congenital intrahepatic portal vein aneurysm in women who had chronic hepatitis. Ultrasound (US) and computed tomography (CT) investigations revealed vascular communication between intrahepatic portal vein and venous aneurysms in both cases. These portal vein aneurysms were fusiform in shape and two and one centimeter in diameter in each case. On angiography portal-hepatic venous shunt was observed in one case. The MR image of two cases were presented. We believe this is the first report of MR image of portal vein aneurysm.
