A 1-year-old boy presented with bladder mass which proved to be embryonal rhabdomyosarcoma came for assessment of treatment response. a Prechemotherapy axial CT (left), axial PET (middle), and axial fused PET/CT (right) revealed metabolically active FDG avid primary mass (with SUV = 5.4). b Postchemotherapy axial CT (left), axial PET (middle), and axial fused PET/CT (right) revealed regression of the FDG uptake (SUV = 3.6). Radical cystectomy was done and the pathology showed that there was 85% viable tumor (poor responder)
