Images in a 55-year-old male patient with a history of hepatitis C virus-related cirrhosis and a 45-mm hepatocellular carcinoma (HCC). Axial (A) precontrast and (B-D) contrast-enhanced CT images in the (B) hepatic arterial, (C) portal venous, and (D) delayed phases show lesion (arrow in B) with rim arterial phase hyperenhancement categorized as LI-RADS category LR-M. (E) Photograph of resected specimen shows a poorly demarcated HCC. (F) Photomicrograph (hematoxylin-eosin stain) reveals a poorly differentiated HCC with microvascular invasion (arrows). Scale bar in F = 600 µm. Intrahepatic recurrence was observed at 14 months after resection. Image courtesy of the RSNA.
