Case 95:   Hepatocellular Carcinoma (HCC)

Diagnostic Category:

Clinical Presentation:

54 year old man presents with jaundice.

CT: Infiltrative HCC in cirrhosis with left portal vein invasion

Imaging Findings:

Multiphase CT reveals cirrhosis and infiltrative hepatocellular carcinoma will ill defined borders mainly in segment 4 of the left lobe. Typical for diffuse HCC is the absence of a well-defined mass. There is also no pseudocapsule. Notice invasion of the left portal vein (arrow) causing hypervascular perfusion abnormalities around and in between the foci of HCC.

A low density area in the right lobe represents a radiofrequency ablation (RFA) site, which is also surrounded by a hypervascular THAD.
