Abstract:
The tumor drainage pathway of a hypervascular liver tumor without fibrous capsule was evaluated histologically and using single-level dynamic CT during hepatic arteriography (CTHA) in a case of sclerosing type of hepatocellular carcinoma. This tumor had a thin corona on CTHA, which represented drainage from the tumor sinusoids to the surrounding liver sinusoids. Additionally, the corona of the hypervascular tumor was thinner without than with the fibrous capsule.
