Synchronous inverted papilloma of bladder and renal pelvis.

Inverted papilloma of the urinary tract is a rare tumor that consists of uniform urothelial cells with an inverted configuration and a normal urothelial lining.

We detail a case of synchronous inverted papilloma of the urinary bladder and the renal pelvis and review the published data.

A case, which is clinically characterized by a subacute vertebrobasilar syndrome, is presented. The necropsy reveals multiple infarcts in brainstem, cerebellum and left cerebral hemisphere, due to tumoural emboli of a non-detected primary tumour. It is postulated that the latter has to originate in the lungs in order to produce this unique type of cerebral arterial embolism.
