title: Multiple skeletal metastases of Ewing's sarcoma demonstrated on FDG-PET and compared with bone and gallium scans.
abstract: Bone and gallium scans have been shown to be useful in imaging Ewing's sarcoma. Here we report on a case of recurrent Ewing's sarcoma with multiple skeletal metastases demonstrated by the FDG-PET whole body scan, while the bone scan revealed fewer lesions and a non-remarkable finding was found on the gallium scan. The following pathologic examination showed bone marrow involvement. This case demonstrated that the FDG-PET could detect more lesions of metastatic Ewing's sarcoma than bone and gallium scans, especially for those with bone marrow involvement.
