Strangulated appendiceal intussusception caused by isolated endometriosis

A 33-year-old female was admitted to our emergency department for right lower quadrant abdominal pain, which was not associated with her menstrual cycle, and nausea, which had persisted for 3 days. She denied any prior history of abdominal pain, dysmenorrhea, menorrhagia, or dyspareunia. The patient had no family history of endometriosis. Abdominal computed tomography revealed appendiceal intussusception (AI) and invagination of the periappendiceal fat into the cecum. She underwent laparoscopic partial cecectomy with the presumed diagnosis of AI. The ovaries and fallopian tubes were normal, with no endometrial spot. The inverted appendix was completely necrotic. Final surgical pathology was positive for gangrenous intussusception of the appendix, with endometrial deposits. KCI Citation Count: 0
