Giant avascular hepatocellular carcinoma mimicking metastatic tumor

We have described the radiographic features of a case of solitary giant hepatocellular carcinoma in a noncirrhotic liver. It was angiographically avascular and resembled a massive metastatic tumor. Most hepatocellular carcinomas appear highly vascular on angiography. Hypovascularity may sometimes be encountered in the presence of cirrhosis.
