Hepatic angiosarcoma with early central enhancement and arterioportal shunt on dynamic CT

Abstract

We report a case of hepatic angiosarcoma that is usually difficult to differentiate from cavernous hemangioma on computed tomography. The present case suggests that early central enhancement and arterioportal shunting on dynamic computed tomography might be helpful for distinguishing hepatic angiosarcoma with a solid growth pattern from benign vascular neoplasms of the liver such as cavernous hemangioma.
