Vesicocervical fistula: rare complication of cesarean section demonstrated by magnetic resonance imaging.

We report a rare complication of cesarean section in a 46-year-old woman presenting with incontinence. The patient was noted at cystoscopy to have a lesion on the posterior wall of the bladder. Histologic examination of the biopsied lesion demonstrated endocervical tissue, and subsequent magnetic resonance imaging revealed a vesicocervical fistula. She was treated by open excision of the fistula and repair of the bladder and cervix with omental interposition. Only 16 cases of vesicocervical fistulas have been previously reported, and this is the first to demonstrate the finding on magnetic resonance imaging.
