title: Appendiceal intussusception masquerading as an ileocolic intussusception.
abstract: BACKGROUND
  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.
  
  
  METHODS
  One-quarter of cases occur in the pediatric population where it is usually due to appendiceal inflammation.
  
  
  CONCLUSIONS
  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.
