title: Primary liver tumors in the pediatric age group: an angiographic challenge.
abstract: Eleven children, ranging in age from three months to fifteen years, with primary liver tumors were examined by large volume direct magnification arteriography (2.5--3 ml of contrast material per 1 kg body weight for a single selective study). The following tumors were found: hepatoblastoma (1), hepatocellular carcinoma of the adult type, hepatoma (3), infantile hemangioendothelioma (4), hemangiosarcoma (1), focal nodular hyperplasia (1) and cystic mesenchymal hamartoma (1). Some of the tumors have a quite typical angiographic appearance as infantile hemangioendothelioma, hemangiosarcoma, cystic mesenchymal hamartoma. The other highly vascular neoplasms show unspecific signs of vascular malignant tumors; subtile angiographic signs may, however, be present and help in the differential diagnosis.
