Dermoid cysts are the most common type of ovarian tumors of all primary ovarian tumors. We present a 55-year-old postmenopausal woman, who admitted to the emergency clinic due to abdominopelvic pain. Abdominopelvic computed tomography scan showed a lesion measured 15X11 cm and no other pathology observed in any of the other abdominal organs. She underwent exploratory laparatomy and a cystic mass complicated with a three times torsion of left ovary and fallopian tube was observed. Left salphingoopherectomy was performed. While explorating the abdomen, a solid cystic mass palpated which was a segment of the ileum leading to necrosis and thought to be caused by the ovarian torsion pushing or twisting the ileum mesentery. After applying warm compress and revising the mesentery of the ileum, the blood flow returned and colour changed to pink. So, we decided not to perform ileal resection. The patient complained severe abdominal pain two days after the operation. She underwent second laparotomy. A necrosed segment of the ileum was seen and 40 cm ileal segmental resection was performed. Consequently, it should be kept in mind that intestinal pathologies could be concurrently seen during the diagnostic work up of gynecologic disorders presenting with acute abdominopelvic pain. However, we strongly recommend to explore the whole abdomen during the operation regardless of the index diagnosis.
