CT on diagnosis and differential diagnosis of adrenal neuroblastoma from nephroblastoma in children

Objective: To evaluate the effect of CT on diagnosis and differential diagnosis of children's adrenal neuroblastoma from nephroblastoma. Materials and Method: To analyse the CT manifestations on 36 cases of adrenal neuroblastoma and 32 cases of nephroblastoma both confirmed by postoperative pathologic diagnosis. Results: The adrenal neuroblastoma is a kind of extrarenal tumor, so the kidney kept its original form and showed some compressive features. The incidence of tumor calcification appeared mostly in rough and speckle-piece form was high. While the nephroblastoma is a renal tumor. The surrounding renal parenchyma showed a specific 'new-moon shape' intensification. Conclusion: CT is one of the most valuable and effective means of examination to diagnose adrenal neuroblastoma and differentiate it from nephroblastoma. It can provide important information for making correct diagnosis, planning proper therapy and assessing prognosis
