The practice of routinely evaluating the portal vein as part of a right upper quadrant sonography study may have value as a screening mechanism for portal vein thrombosis. Difficulties arise in differentiating thrombosis from tumor as the source of portal vein obstruction. This case study of portal tumor thrombosis (PTT) due to hepatocellular carcinoma is a good example of the use of multiple modalities to arrive at the definitive diagnosis. Many studies have been conducted on the effectiveness of magnetic resonance imaging and computed tomography on the accurate diagnosis of PTT, but few cases have been reported that used a multimodality approach.

Key Words: hepatocellular carcinoma • portal tumor thrombosis • color Doppler
