Salpingovesical fistula mimicking an enterovaginal fistula.

Fallopian tube fistula with the bladder can mimic an enterovaginal fistula. A 34-year-old woman presented with continuous urinary incontinence after hysterectomy. A cystogram confirmed a vesicovaginal fistula and a possible additional intestinal communication. Further imaging, however, ruled out an enterovaginal fistula and diagnosed a fallopian tube prolapse with salpingovesicovaginal fistula. This case demonstrates the importance of multiple imaging modalities in identifying and clearly delineating the anatomy of gynecologic fistulous connections. The case illustrates the fact that while salpingovesical fistula is a rare complication of hysterectomy, it is an important consideration in one's differential diagnosis.
