Intraperitoneal hepatocellular carcinomatosis

The sonographic and computed tomographic features of liver involvement with hepatocellular carcinoma are well known.

We present a case in which intraperitoneal carcinomatosis and portal vein thrombosis were the dominant findings on sonography and computed tomography.
