title: Cavernous hemangioma with arterioportal and arterio-hepatic vein shunts coexisting with hepatocellular carcinoma.
abstract: A patient with hepatocellular carcinoma (HCC) and coexisting hepatic cavernous hemangiomas with arterioportal and arterio-hepatic vein shunts is reported. Antegrade and retrograde opacifications of portal vein radicles and filling of a branch of the right hepatic vein verging on cavernous hemangiomas were observed in the late arterial phase of hepatic arteriography in addition to HCC. Unenhanced CT scans performed eight days after the arterial infusion of Lipiodol showed clearly the location of the tumors and the shunting vessels. To the authors' knowledge, this is the first reported case of cavernous hemangioma with arterioportal and arterio-hepatic vein shunts accompanied by hepatocellular carcinoma.
