Appendiceal duplication in children presenting as an appendiceal tumor and as recurrent intussusception.

Duplication of the appendix is a rare condition and is usually an incidental finding during an appendectomy. There have been several cases reported in the literature. Although not usually associated with any discrete pathology, the presenting symptoms can vary but are usually associated with acute appendicitis. We present two cases of appendiceal duplication in young children, one presenting with the usual signs and symptoms of acute appendicitis and the other with intussusception. The purpose of this report is to present two distinct modes of presentation of this rare condition so that pediatric general surgeons are aware of this as a possible entity.
