A rare adult renal neuroblastoma better imaged by18F-FDG than by68Ga-dotanoc in the PET/CT scan.
Primary renal neuroblastoma is an uncommon tumor in children and extremely rare in adults. We present a case of a middle aged female having a large retroperitoneal mass involving the right kidney with features of neuroblastoma on pre-operative histopathology. Whole-body fluorine-18-fluoro-deoxyglucose positron emission tomography (18F-FDG PET/CT) and68Ga-dotanoc PET/CT scans performed for staging and therapeutic potential revealed a tracer avid mass replacing the right kidney and also pelvic lymph nodes. The18F-FDG PET/CT scan showed better both the primary lesion and the metastases in the pelvic lymph nodes than the68Ga-dotanoc scan supporting diagnosis and treatment planning.
