Giant infantile hemangioendothelioma of the liver. Scintigraphic diagnosis.

Abstract

Infantile hemangioendothelioma of the liver is benign mesenchymal tumor composed of anastomosing vascular channels lined with plump endothelial cells. It is a congenital lesion noted at birth or during the first 6 months of life. The authors report a large infantile hemangioendothelioma that was imaged with anatomical modalities and Tc-99m RBC scintigraphy. An early "blush" on Tc-99m RBC hepatic scintigraphy is a diagnostic feature of infantile hemangioendothelioma.
