Scintigraphic findings in infantile hemangioendothelioma

The scintigraphic findings on sulfur colloid liver-spleen imaging, Tc-99m labeled RBC blood pool imaging, and Tc-99m MDP bone imaging in four patients with infantile hemangioendothelioma are described. Thirteen radionuclide studies were performed, with serial sulfur colloid images obtained in three patients, allowing interval assessment of liver size and tumor involvement. Findings of Tc-99m MDP uptake in the livers of two patients with hemangioendothelioma and diffuse increase in hepatic RBC labeled blood pool activity in one patient also are reported.
