Case 344: Hepatocellular Carcinoma (HCC)
64 year old man with history of chronic hepatitis C.
CT: Typical, without equilibrium phase
CT demonstrates cirrhosis with HCC: a subtle area of ill-defined arterial enhancement in segment 5 with very subtle washout on the portal venous phase as marked by arrows. There is a small central hypodensity, representing necrosis or scar. This was further evaluated with MR, which shows more typical criteria for HCC on the equilibrium phase.
