A case of atypical caudate lobe hemangioma mimicking hepatocellular carcinoma: CT and angiographic manifestations

Figure 1 CT images were obtained from an asymptomatic 58-year-old woman with an atypical hepatic hemangioma. A: A 4.0 cm × 4.6 cm caudate lobe mass, which exhibits a subtle, discontinuous peripheral thin-rim enhancement (attenuation value of 76 HU) shown by post-contrast triphasic CT scan at the arterial-phase. B and C: A moderately increased enhancement degree and a widened enhancement thickness for the enhanced peripheral zone (attenuation value of 110 to 114 HU) in the caudate lobe mass shown by post-contrast triphasic CT scans at the portal-phase and delayed-phase.

Figure 2 Peripheral tumor stains during the late arterial phase and foci of spotty lipiodol retention in the peripheral and central portions of the caudate lobe mass. A: Peripheral tumor stains during the late arterial phase. B: Foci of spotty lipiodol retention in the peripheral and central portions of the caudate lobe mass.
