A vaginal septum is a vaginal anomaly that is partition within the vagina; such a septum could be either longitudinal or transverse. In some affected women, the septum is partial or does not extend the length or width of the vagina.[1] Pain during intercourse can be a symptom. A longitudinal vaginal septum develops during embryogenesis when there is an incomplete fusion of the lower parts of the two Müllerian ducts. As a result, there may appear to be two openings to the vagina. There may be associated duplications of the more cranial parts of the Müllerian derivatives, a double cervix, and either a uterine septum or uterus didelphys (double uterus).[1][2] A transverse septum forms during embryogenesis when the Müllerian ducts do not fuse to the urogenital sinus. A complete transverse septum can occur across the vagina at different levels. Menstrual flow can be blocked,[3] and is a cause of primary amenorrhea. The accumulation of menstrual debris behind the septum is termed cryptomenorrhea. Some transverse septa are incomplete and may lead to dyspareunia or obstruction in labour.[4][5]
