Ileocecal intussusception extending to left colon due to endometriosis.

Bowel involvement in endometriosis is uncommon and is most frequently located in the sigmoid colon and the rectum. We present a case in a 37-year-old woman of a cecal endometrioid mass complicated with an ileocolic intussusception which extended beyond the splenic colon flexure. Careful manual extraction allowed a reduction of the intussusceptum, followed by an oncological right hemicolectomy. The patient suffered postoperative ileus, which was spontaneously solved. Intussusception is infrequent in the adult population and usually involves the small bowel. The great majority of ileocolic intussusceptions have a malignant origin (cecal adenocarcinoma). An endometriotic mass located at the cecum as the lead point for ileocolic intussusception is an extremely rare presentation. On reviewing the literature, we found only 13 reports with no other cases extending beyond the splenic flexure, as occurred in our patient.
