Fig. 3C —79-year-old man with hepatic steatosis and hepatocellular
carcinoma. Peritumoral sparing of fatty infiltration is present around
hepatocellular carcinoma. Contrast-enhanced hepatic arterial phase CT scan
shows enhancing tumor surrounded by wedge-shaped parenchymal enhancement
(arrowheads) in right hepatic lobe. It is not definite whether this
type of temporal enhancement indicates arterioportal shunt or corona-like
enhancement. Diagnosis of hepatocellular carcinoma was made after percutaneous
biopsy of tumor.
