Appendiceal intussusception masquerading as an ileocolic intussusception.

INTRODUCTION: Appendiceal intussusception is rare occurring with an incidence of 0.1%. It is most commonly encountered in middle-aged females due to endometrial involvement of the appendix. CLINICAL DATA: One-quarter of cases occur in the pediatric population where it is usually due to appendiceal inflammation. DISCUSSION: Classification of appendiceal intussusception (type I-V) is based on the level of appendiceal invagination. Appendectomy is the treatment of choice unless there is a concern for a neoplasm in which case a more extensive resection may be necessary. We report a 47-year-old with an appendiceal intussusception.
