The authors present an angiographic and a histologic evaluation of 8 cases of pediatric hepatic tumors.The angiographic features of hepatoblastoma were similar to those of adult hepatoma. Prolonged pooling of contrast material in vascular spaces and early shunting of contrast material into the hepatic vein were important features of benign hepatic tumors.The differences between adult hemangioma and infantile hemangioendothelioma are discussed.
