<prompt> Neuroblastoma differs from Wilms tumor radiologically by all exceptCalcificationAorta and IVC are not eroded but pushed asideSame locationIntraspinal extension of tumor  <response>: The following are the differentiating feature bw Neuroblastoma Wilms tumor.CalcificationThere are foci of calcifications visible in neuroblastoma about 85 which are generally less common and less prominent in Wilms tumor less than 15.Intraspinal extensionThe intraspinal extension is seen in neuroblastoma, not in Wilms tumor.Aorta WC invasionWilms tumor invades Aorta and IVC. Whereas Neuroblastoma does not invade these structures.LocationWilms tumor and neuroblastom can be differentiated on location too. C.T. findings will confirm the intrarenal location of Wilms. Whereas Neuroblastoma will be seen above the kidney pushing it downwards outwards.Crossing midlineWilms tumoror are typically confined to one side of the abdomen, whereas neuroblastomas usually cross the midline.
