Report of a Case.—A 71-year-old man was hospitalized because of anemia and guaiacpositive stools. Barium enema examination revealed a small filling defect in the cecum, possibly carcinoma. At the time of operation, the distal appendix was intussuscepted into the proximal appendix and cecum (Figure). The intussusception was released by sharp dissection of adhesions on the appendiceal surface and an appendectomy was performed. The midappendix contained a cystic mass diagnosed as mucocele.

Comment.—Appendiceal intussusception is more common in children, but has occurred in patients aged from 10 months to 85 years.
