title: Preterm torsion of a gravid uterus didelphys horn of a twin pregnancy.
abstract: BACKGROUND
  Simultaneous pregnancy in each horn of a uterus didelphys is a rare and complex clinical situation.
  
  
  METHODS
  Torsion of one horn of a gravid didelphic uterus during a twin pregnancy was diagnosed during cesarean delivery after erroneous diagnosis of abruptio placentae.
  
  
  CONCLUSIONS
  Localization of the placenta in a pregnancy complicated by uterine didelphys may improve the ability to diagnose hemiuterus torsion.
