Ovarian cyst torsion is a well-known cause of acute abdominal pain in female patients. However, torsion of a normal ovary is extremely rare and predominantly occurs in premenarchal female patients. The objective of this report is to describe a rare case of acute abdomen during the early postpartum period that was ultimately diagnosed as torsion of a normal ovary by laparoscopic surgery. A 29-year-old woman vaginally delivered a healthy 3530-g baby uneventfully at 40 weeks’ gestation. On postpartum day 6, she presented with acute abdominal pain in the right lower quadrant and costovertebral angle tenderness. A complete workup including laboratory examination, ultrasonography, and computed tomography was performed. Leukocytosis with a left shift and a slightly enlarged right ovary were found. Finally, diagnostic laparoscopy showed torsion of a normal ovary. The patient underwent laparoscopic detorsion of the right adnexa and was discharged on postoperative day 4 without any complications.
