Bladder origin neuroblastoma detected by mass screening.

Pelvic neuroblastoma is relatively rare and most are a presacral mass. We present a case of asymptomatic neuroblastoma arising from the dome of the bladder wall, detected by a mass screening program. Only 1 case of neuroblastoma originating from the bladder has been previously reported. Both the reported case and our present case arose from the dome of the bladder wall. The differential diagnosis for bladder tumor in children is discussed; although uncommon, neuroblastoma should be considered a probable choice, especially for tumors arising from the dome of the bladder wall.
