Preterm Torsion of a Gravid Uterus Didelphys Horn of a Twin Pregnancy

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