The diagnosis of a colovaginal fistula with intravaginal sonography

This case study involves a patient with diverticulitis presenting with a secondary complication of a colovaginal fistula. The most common cause of colovaginal fistulas is diverticulitis. Patients older than age 80 and those who have had a hysterectomy are at an increased risk of developing a colovaginal fistula. Common manifestations include feces and gas passing via the vagina and severe vaginitis. There are different imaging methods and modalities used to demonstrate and localize colovaginal fistulas. This study used intravaginal sonography as the primary diagnostic tool.
