Portal-hepatic venous malformation: ultrasound, computed tomographic, and angiographic findings.
A 59-year-old woman was evaluated for a mass in the right lobe of the liver. Ultrasonography (US) demonstrated multiple anechoic areas with enlargement of portal and hepatic veins. These areas were enhanced uniformly after bolus injection of contrast material during computed tomography (CT). The diagnosis of portal-hepatic venous fistula was confirmed by the portal venous phase of a superior mesenteric angiogram.
