The transverse vaginal septum is a congenital Mullerian abnormality caused due to improper fusion of the Müllerian ducts with urogenital sinus. It is classified as complete or incomplete and obstructive or non-obstructive and occurs at various levels such as superior vaginal (46%), mid-vaginal(40%) and inferior vaginal(14%). Transverse vaginal septum is a rare condition with incidence varying from 1:2100 to 1:72,000. The condition is difficult to manage often due to delayed diagnosis and is usually diagnosed when hematocolpos lead to symptoms due to an expanding pelvic mass
