Patient with hepatocellular carcinoma (HCC) in his/her forties. T1WI (a) and T2WI (b) images showing heterogeneous signals in the tumor. Intratumoral vessels are visible on the arterial phase (c, arrow), and the delayed phase shows an incomplete tumor capsule (d). The tumor was of multinodular type with maximum diameter 67 mm, and peritumoral hypointensity (arrow) is seen on the hepatobiliary phase (e-g). The pathologic result of hematoxylin and eosin staining of a tumor tissue section (h) was medium-differentiated HCC
