A 13-year-old boy presented with urinary bladder mass; the mass was proven by a biopsy to be embryonal rhabdomyosarcoma. a Prechemotherapy axial CT (left), axial PET (middle), and axial fused PET/CT (right) revealed metabolically active FDG avid 1ry tumor lesion (SUV = 2.9). b Postchemotherapy axial CT (left), axial PET (middle), and axial fused PET/CT (right) revealed marked regression of the FDG uptake (SUV = 1.5) as well as moderate size regression. The mass was excised without tumor viability detected on histopathology
