Appendiceal intussusception from endometriosis

Abstract

  Appendiceal intussusception secondary to endometriosis is extremely rare. We report a case of left ovarian endometriosis with endometriosis-induced appendiceal intussusception in a 42-year-old woman presenting with rectal bleeding and left-sided abdominal pain. Colonoscopy revealed a cecal mass measuring 30 mm in diameter. Magnetic resonance imaging revealed extensive pelvic adhesions and a left-sided endometrioma measuring 20 mm in diameter. Laparoscopy revealed isolated appendiceal intussusception and deep infiltrating pelvic endometriosis. Laparoscopic ileocecal resection and left ovarian cystectomy were performed. Histopathological examination confirmed the diagnosis of ovarian endometriosis with endometriosis-induced appendiceal intussusception. Although rare, endometriosis-induced appendiceal intussusception should be considered in the differential diagnosis in women with endometriosis presenting with an appendiceal mass. Coordination between gynecologists and gastrointestinal surgeons is essential for an effective surgical approach to ensure optimal management.
