A case of liver capillary hemangioma with cystic lesions

Hepatic capillary hemangioma is a rare hepatic benign tumor which composed of the aggregation of capillary vessels. Because of the difficulty of diagnosis, there are some reports diagnosed by surgical resection. We reported the case of liver capillary hemangioma with cystic lesions which was diagnosed by single level dynamic CT and fine-needle targeted biopsy. A patient was female in the sixties. Screening examination by magnetic resonance imaging (MRI) pointed out the tumor in the 6th segment of liver. Contrast enhanced CT revealed that tumor was strongly enhanced in the arterial phase. Washout pattern was observed at equilibrium phase. Single level dynamic CT during hepatic arteriography showed spotted enhanced followed to enhanced homogeneously, which might reveal the characteristic of capillary vessels in the tumor. The tumor tissue obtained by fine-needle biopsy showed the aggregation of capillary vessels positively immuno-stained with CD34 and factor VIII, that lead to diagnose hepatic capillary hemangioma.
