A relationship between schistosomiasis japonica and hepatocellular carcinoma has been reported. However, there have been no reports of hemangioma of the liver associated with schistosomiasis japonica. A 64-year-old man was diagnosed as having hepatocellular carcinoma by CT, echo, MRI and angiography. It was localized to the posterior segment of the liver, and he was subjected to posterior segmentectomy. Histological examination of the resected specimen showed calcified ova in the portal area, and the tumor consisted of a venous hemangioma. It was difficult to diagnose as a hemangioma because of the peripheral, small-type and long-term accumulation of lipiodol in the tumor. It appeared that a type of portal hypertension caused by the calcified ova of Schistosoma japonicum in the portal area made it impossible to wash out the lipiodol.
