A case report of torsion of the gravid uterus caused by pelvic adhesion.

Key Clinical Message: In this case, a patient experienced rare uterine torsion during pregnancy, detected by MRI. Diagnosis before Cesarean is helpful to achieve better outcomes, highlighting the importance of attention in high-risk groups.

Abstract: Uterine torsion during pregnancy is a rare complication and its risk factors and diagnostic modalities have not yet been clearly defined. Here we present a case of uterine torsion due to unexpected pelvic adhesion. A 34-years-old primigravida patient underwent an emergency cesarean section for aggravated maternal preeclampsia symptoms at 34 + 0 weeks of gestation. Intraoperatively, after the baby was out, it was found that the uterus was rotated about 90 degrees to the right by dense pelvic adhesion in posterior uterine wall. In this patient, a rightward vaginal stretch was represented through a retrospective review of magnetic resonance imaging (MRI) before childbirth. To our knowledge, this is the first reported case of uterine torsion during pregnancy with MRI. Diagnosing uterine torsion in advance or paying attention to incisions during operative delivery will lead to better management in this condition and good perinatal outcomes.
