A 17-year-old male with right femoral Ewing sarcoma. a Prechemotherapy coronal CT (left), PET/CT (middle) showed right femoral metabolically active FDG avid lesion with SUV about 4.7. X-ray (right) revealed posterior distal femoral lesion with a wide zone of transition and aggressive periosteal reaction. b Postchemotherapy coronal PET (left), PET/CT (middle) revealed metabolic regression regarding the distal femoral mass lesion (SUV 2.3). The patient underwent limb salvage surgery and pathological assessment revealed 95% tissue necrosis (good responder). No morphologic changes regarding conventional imaging features (right)
