title: Brain and bone scans in primary Ewing's sarcoma of the petrous bone.
abstract: The authors present a case in which primary Ewing's sarcoma of the right petrous pyramid in a 9-year-old girl showed no uptake on a 99mTc-pertechnetate nuclide angiogram. Intense uptake was present on a 99mTc-polyphosphate bone scan, but a static brain scan was only minimally abnormal. The diagnosis and treatment of Ewing's sarcoma are reviewed.
