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 (F-FDG PET/CT) and Ga-dotanoc PET/CT scans performed for staging and therapeutic potential revealed a tracer avid mass replacing the right kidney and also pelvic lymph nodes. The F-FDG PET/CT scan showed better both the primary lesion and the metastases in the pelvic lymph nodes than the Ga-dotanoc scan supporting diagnosis and treatment planning.
原发性肾神经母细胞瘤在儿童中是一种罕见肿瘤，在成人中极为罕见。我们报告一例中年女性病例，其腹膜后有一巨大肿块累及右肾，术前组织病理学检查具有神经母细胞瘤特征。为进行分期及评估治疗潜力而进行的全身氟-18-氟脱氧葡萄糖正电子发射断层扫描（F-FDG PET/CT）和镓-多他胺PET/CT扫描显示，有一个摄取示踪剂的肿块取代了右肾及盆腔淋巴结。F-FDG PET/CT扫描在显示原发灶及盆腔淋巴结转移方面比镓-多他胺扫描更好，有助于诊断和治疗规划。
