Abstract
- A Wilms' tumor is the most common solid intrarenal neoplasm during childhood. Therefore, any renal mass found in a child is considered to be a Wilms' tumor, until proven otherwise. An intrarenal neuroblastoma is very rare and believed to originate from adrenal rests found within renal tissue, or from intrarenal sympathetic ganglia. Some investigators believe intrarenal neuroblastomas are suprarenal tumors that have invaded, and displaced, the kidney. Owing to its rarity, this lesion remains to be fully characterized. We experienced a case of an intrarenal neuroblastoma, which was radiologically confused with a Wilms' tumor.
