Case 160: Angiosarcoma
30 year old man with acute onset of abdominal pain.
CT: Embolized after rupture
CT images shown are post interventional embolization for ruptured, biopsy proven primary hepatic angiosarcoma. Cirrhotic liver with large peripherally hypervascular mass in the right lobe with hypodense necrotic components. Note that tumor and right hepatic lobe are not completely avascular after embolization of the right hepatic artery and residual enhancement on equilibrium phase persists, which proves tumor blood supply through the portal vein. There are also numerous small hypervascular metastases in the left lobe, some of them with vague, but typical ring enhancement.
