Vaginal mullerian cyst presenting as a cystocele.

Abstract

Vaginal cysts occur rarely, are usually discovered incidentally on examination, and can cause a variety of symptoms. This article discusses a 34-year-old para 2 female with a large anterior vaginal wall cyst that arose at 20 weeks' gestation and was originally diagnosed as a cystocele. The unusual timing of its occurrence and the characteristics of the anterior vaginal wall prompted ancillary testing and reexamination. The timing of onset and general characteristics of prolapse as well as defecography and magnetic resonance imaging can be used to aid the gynecologist in diagnosing vaginal cysts instead of the more common condition of vaginal prolapse.
