Extraosseous Uptake and Multiple Metastases of Splenic Composite Hemangioendothelioma on 99mTc-MDP Scintigraphy.Composite hemangioendothelioma is a rare disease that exhibits biological potency ranging from benign to low-grade malignancy, and hepatic and bone metastases are even rarer.  A bone scan revealed abnormal uptake of 99mTc-MDP in multiple bones and spleen, whereas enhanced CT demonstrated splenic lesions with low density and mild enhancement.
