Acute renal failure from a pelvic arteriovenous malformation.

introdUCtion Pelvic arteriovenous malformations (AVM) are rare and may be congenital or acquired and commonly mimic more common disorders. We describe a young adult male with pulmonary complaints who was found to have acute renal failure, hydronephrosis, congestive heart failure and multiple midline pelvic varices secondary to pelvic AVMs. We report this case to alert physicians to the diverse spectrum and diagnostic difficulties of pelvic AVMs.
