title: Hemangioendothelial sarcoma of the sacrum: CT findings.
abstract: A hemangioendothelial sarcoma (angiosarcoma) of the sacrum was discovered by computed tomography (CT) in a patient with a fever of undetermined origin. A CT-directed fine needle biopsy of the lesion helped establish the diagnosis. Plain radiographs revealed only very subtle changes in the sacrum and a bone scan was negative. A literature search revealed no previous descriptions of the CT appearance of this rate primary bone neoplasm.
