| Abstract: | We report a case of hemangioma with an atypical vascular enhancement pattern. The hemangioma showed peripheral rim enhancement at the arterial phase during dynamic magnetic resonance imaging, and the peripheral enhanced zone was still apparent during the delayed phase, as shown on double-phase computed tomography hepatic arteriography. The rim enhancement pattern of this case, mimicking that of hepatocellular carcinoma, may be due to the surrounding liver parenchymal fibrotic change caused by an active hepatitis C viral infection. |
