Non-puerperal uterine inversion is an extremely rare and potentially dangerous condition. Cases are poorly described in the literature, and their actual incidence is unknown. A 34-year-old nulliparous female patient visited the emergency department following a loss of consciousness. She had experienced continuous vaginal bleeding over the preceding two months, with a two-day history of worsening symptoms. The patient showed signs of hypovolemic shock secondary to unceasing vaginal bleeding. Ultrasound and computed tomography revealed an inverted uterus and a large hematoma inside the patient's vaginal cavity. An emergency explorative laparoscopy was performed, which confirmed uterine inversion. Initially, Johnson's maneuver was attempted under laparoscopic visualization, but this failed to achieve uterine reduction. Following the unsuccessful performance of Huntington's maneuver, a re-trial of the manual reduction allowed the uterus to recover to its normal anatomy. The patient's vaginal bleeding was dramatically reduced after successful uterine reduction. The pathologic report conducted confirmed endometrioid adenocarcinoma. Laparoscopic visualization is a feasible and safe procedure for achieving uterine reduction in cases of non-puerperal uterine inversion with an unconfirmed pathology. Uterine malignancies should be considered in patients with non-puerperal uterine inversion.
