Scintigraphic "doughnut sign" on skeletal imaging due to a hemangioendothelioma of bone.
A 61-yr-old patient was referred to our hospital for investigation of pain and tenderness in his left lower limb. Bone scan revealed multiple lesions of tibia and foot, several of which appeared as doughnut-like lesions and corresponded to lytic abnormalities on radiographs. Pathologic examination revealed multiple epithelioid hemangioendothelioma of bone.
