Answer

Answer

Abdominal neuroblastomas usually develop in the retroperitoneum. Most arise from the adrenal gland and displace the kidney inferomedially. In rare cases, a neuroblastoma may mimic a Wilms tumor, arising from tissues in the kidney or invading the kidney. To make diagnosis complicated, rare neuroblastomas possess other features more typical of Wilms tumor than of intrarenal neuroblastomas.
