Uterine torsion in non-gravid women: A case report and review of cases reported in the last 20 years.

Uterine torsion is defined as a rotation of >45° around the long axis of the uterus. Uterine torsion is an uncommon event but is even rarer in non-gravid women, with only 25 cases reported in the last 20 years. Here, we report a case of uterine torsion associated with multiple pedunculated subserosal uterine leiomyomas in an 83-year-old woman. She presented at the hospital with lower abdominal pain, and a computed tomography scan revealed multiple uterine leiomyomas with calcifications. Subsequent magnetic resonance imaging raised suspicion for torsion of pedunculated subserosal uterine leiomyomas. Emergency laparotomy was performed, and the patient was diagnosed with uterine torsion with multiple pedunculated subserosal uterine leiomyomas. Total abdominal hysterectomy and bilateral salpingo-oophorectomy were performed. The patient's postoperative course was uneventful. Although difficult to diagnose due to its rarity, uterine torsion can be life-threatening and may cause infertility. Therefore, early diagnosis with imaging and surgical intervention are crucial to avoid serious complications.
