title: Unique case of successful twin pregnancy after spontaneous conception in a patient with uterus bicornis unicollis.
abstract: BACKGROUND
  Abnormal fusion of the mullerian ducts or failure of absorption of the septum causes varying degrees of congenital uterine malformation. Twin gestation in a case of bicornuate uterus is extremely rare. We are reporting this case because of its extremely rare presentation, where twins have managed to reach term after spontaneous conception.
  
  
  METHODS
  A 28-year-old second gravida, para one was initially diagnosed to have diamniotic dichorionic twins on ultrasound. At term, she was referred to us with severe preeclamptic toxaemia. On examination, she was found to have a bicornuate uterus with one fetus in each horn. Both siblings were successfully delivered by caesarean section. So far, only one similar case has been reported following in vitro fertilisation.
  
  
  CONCLUSIONS
  Although poor reproductive performance has been documented in previous reports of bicornuate uterus with twin gestation, our patient managed to reach term with delivery of healthy siblings by caesarean section.
