Uterine inversion in postmenopausal age: case report

Background: Nonpuerperal uterine inversion is a rare medical condition that many gynecologists might not be encountered even with one case during their entire medical practice. It refers to the expulsion of uterine corpus from the dilated cervix resulting in uterus being turned inside out. There are two kinds of uterine inversion, puerperal and non-puerperal, which the second condition is less common. Acute uterine inversion usually presented by crampy abdominal or pelvic pain, vaginal bleeding, anemia, and even symptoms of severe sepsis. We describe a case of uterine inversion in a postmenopausal woman. Case Presentation: A 66 years old grand multiparous woman (6 normal vaginal delivery) who was menopause since 15 years ago, was referred to the emergency unit of an academic hospital of Mashhad University of Medical Sciences at October 2016 due to postmenopausal uterine bleeding, cramp-like abdominal pain and mass protrusion from the vagina. The vital sign was stable at the first visit but a big non-necrotizing red vaginal mass was protruded from vaginal opening that connected to other soft intravaginal mass. Abdominal ultrasonography revealed the dilated vaginal cuff and some air-fluid levels in the uterine cavity. The patient referred to the operative room and vaginal myomectomy was done with diagnosis of pedunculated submocusal leiomyoma. Then, total abdominal hysterectomy and bilateral salpingo-oophorectomy were performed after the correction of uterine inversion by abdominoperineal approach. Conclusion: Acute uterine inversion is a potentially dangerous condition (due to vaginal bleeding, severe abdominal or pelvic pain, and the possibility of uterine necrosis and even systemic infection). This condition should be considered as an important differential diagnosis as a vaginal mass in the post-menopausal period.
