There is an irregular T2 bright transphincteric fistulous tract communicating the mid and upper portions of the anal canal at 12 o'clock to the distal aspect of the posterior inferior vaginal wall, just above the transverse perineal muscles. The surrounding inflammatory changes do not show soft tissue collections.
The distal portions of the rectum have unremarkable appearances for this protocol.
This case illustrates a fistulous tract between the anal canal and distal posterior wall of the vagina consistent with an anovaginal fistula.
