Hepatic arteriography in 2 patients with liver hemangiomas is discussed. One case is an infant with multiple hemangioendotheliomas of the skin and liver, the other case is a woman with multiple cavernous hemangiomas limited to the liver. In both cases, the hepatic artery ramifies normally down to branches of approximately 1 mm. size from which abnormal vessels quickly fill; also, the abnormal vessels remain opacified longer than adjacent normal ones. However, there are marked differences in the appearance of the abnormal vessels in the 2 cases. The liver with cavernous hemangiomas shows clusters of opacified venous lakes along the course of the feeding arterial branches. In the infant with hemangioendotheliomas, the abnormal vessels seem to wrap around multiple avascular centers producing a lobulated pattern throughout the liver.
