Traumatic anovulval fistula

Discussion:

The patient history was  chronic fecal discharges from the perineum. The primary diagnosis was an anovaginal fistula, she was referred for a fluoroscopy exam.

The fluoroscopy exam findings were not so obvious, because the fistulous tract length was short (less than 10mm), and its diameter was wide measuring 4 mm, so that the contrast leaked quickly into the perineum. Gynecological exam reveals a vulval fistulous opening at the posterior valval wall. MRI for anovulval fistula is more sensitive than fluoroscopy.
