Appendix intussusception in a young patient with Crohn's disease

Summary Appendix intussusception is rare, can be responsible of chronic unexplained abdominal pain and is mostly associated with inflammatory changes or endometriosis. A 23-year-old woman with Crohn's disease was diagnosed invaginated appendix by CT-scan and colonoscopy after several acute atypical abdominal pain episodes. These episodes were suspected to be independent of the Crohn's disease and to be attributed to the intussusception itself. A resection combining ligation of the base by colonoscopy and cecectomy by laparoscopy was performed successfully. However, no argument for Crohn's disease was found on the pathologic examination.
