Diagnostic imaging findings upon first admission. Dynamic abdominal CT imaging reveals an 8-cm mass projecting from the liver. Contrast enhancement is mainly on the border, and it is observed in the early phase (a) until the late phase (b). In the early phase, a low-density area in the tumor is considered as a central stellate scar (arrow). Dynamic abdominal MRI shows contrast enhancement in the early phase (c) until the hepatobiliary phase (d)
