Key result
In a 9-year-old girl with primary Ewing's sarcoma of the right petrous bone, a 99mTc-polyphosphate bone scan showed intense uptake while a 99mTc-pertechnetate brain scan was only minimally abnormal.

Ewing's sarcoma of the petrous bone may show intense uptake on bone scans but minimal abnormality on brain scans or nuclide angiograms.
This case suggests distinct scintigraphic patterns in rare petrous Ewing's sarcoma; leaves open diagnostic utility of bone scans in similar skull base tumors.
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.

Fitzer et al. (1976) conducted a case report in Primary Ewing's sarcoma of the petrous bone (n=1). 99mTc-polyphosphate bone scan and 99mTc-pertechnetate brain scan was evaluated on Radionuclide uptake on scans. In a 9-year-old girl with primary Ewing's sarcoma of the right petrous bone, a 99mTc-polyphosphate bone scan showed intense uptake while a 99mTc-pertechnetate brain scan was only minimally abnormal.
