Australian doctors are reporting the case of a woman with two uteri who spontaneously conceived twins, with a fetus in each uterine cavity.

The 35-year-old nulliparous WA woman had been diagnosed with a complete uterine didelphys — two uteri, two cervices and a vaginal septum — as an adolescent.

The vaginal septum was resected when she was 29, report doctors from the King Edward Memorial Hospital for Women in Perth, writing in BMJ Case Reports.

She subsequently conceived naturally and an initial ultrasound at eight weeks revealed a fetus in each uterine cavity.
