Background: Uterine torsion has been associated with a variety of adverse outcomes ranging from fetal distress to maternal death. Uterine torsion has also been reported in otherwise uncomplicated pregnancies.
Cases: We report 2 cases of uterine torsion with abnormal anterior placentation identified at cesarean section, which had previously been disguised as posterior placenta previas.
Conclusion: Given the increased risk of placenta accreta with an anterior placenta and prior cesarean scar, uterine position should be considered in the evaluation of a presumed posterior placenta, particularly with ultrasound findings suggestive of accreta such as placental lakes.
