CT Features of Extrahepatic Growing Hepatocellular Carcinoma Located in the Portacaval Space

摘要

To evaluate the computed tomography (CT) features of the extrahepatic growing hepatocellular carcinoma (HCC) located in the portacaval space. Eleven cases of extrahepatic growing hepatocellular carcinoma in the portacaval space were reviewed retrospectively which were proved by clinical and laboratory findings. Emphasis was placed on the CT features of the masses. 11 cases invaded all the portion of the portacaval space. 11 cases extrahepatic growing hepatocellular carcinoma arose from the liver and had no peduncle. The tumors showed enhancement in the early stage and quick return to hypodensity in the portal vein phase accompany with liver cirrhosis, splenomegaly and enlargement of the lymph nodes. CT is helpful in making accurate diagnosis of the extrahepatic growing hepatocellular carcinoma located in the portacaval space.
