Appendiceal polyp as a lead point for an appendico-colic intussusception requiring operative reduction

Abstract Intussusception of the appendix is a rare condition. When intussusception occurs in the pediatric age group, the intussusceptum usually involves the ileum, cecum or colon. The majority of cases of pediatric intussusception are idiopathic, without a pathologic lead point, and polyps are an uncommon focus of invagination. In this case report, we describe a three year-old female with known Juvenile Polyposis Syndrome (JPS) who presented to our Emergency Department with an appendico-colic intussusception in the right lower quadrant, extending to the right upper quadrant of the abdomen. The patient underwent a surgical reduction of the intussusception and an appendiceal polyp was noted to be the pathologic lead point. The case highlights a highly unusual presentation of intussusception and the surgical management utilized.
