Doctors are being urged to consider a transverse vaginal septum in patients with secondary amenorrhoea, following a recent case involving a young woman with an unusual presentation.

A transverse vaginal septum usually presents at an early age as primary amenorrhoea with cyclical abdominal pain or later as dyspareunia and infertility, write doctors from the All India Institute of Medical Sciences in Jodhpur, India.

But in this case, the 22-year-old woman underwent menarche at 15 and experienced regular menstrual cycles with scanty flow not associated with dysmenorrhea, until a year before presentation when her cycle became irregular.

Her secondary sexual characters were well developed with Tanner stage 4 for both breast development and pubic hair development, they wrote in BMJ Case Reports.
