Magnetic resonance imaging and hysteroscopy to diagnose colo-uterine fistula: a rare complication of diverticulitis.

Colo-uterine fistula of diverticular origin is an extremely rare disease due to the resistance of uterine tissue. Methods for diagnosis remain to be established. Non-invasive imaging like magnetic resonance imaging (MRI) may help to establish a proper diagnosis, but confirmation may be reached by diagnostic hysteroscopy or even surgical exploration.
