Neuroblastoma is the tumor of sympathetic nervous system that derives from primordial neural crest cells. Neuroblastoma is the third most common pediatric malignancy after leukemia and central nervous system tumors. This article reported atypical computed tomographic findings of neuroblastoma with massive intra-abdominal and retroperitoneal lymphadenopathy. The authors reported a 2-year-old girl who presented with abdominal distension and fever. Ultrasonographic examination showed a large heterogeneous echogenic mass at right suprarenal region. Contrast enhanced computed tomography (CT) of the whole abdomen revealed an ill-defined inhomogeneous enhancing mass at right adrenal gland with internal calcification. There were massive intra-abdominal and retroperitoneal lymphadenopathy. Pathological diagnosis showed the poorly differentiated neuroblastic tumor. This article reported atypical CT findings and reviews natural history, histological findings, biological features, and radiographic appearances.
