Cecal polyp and appendiceal intussusception in a child with recurrent abdominal pain: diagnosis by colonoscopy.

A 7-year-old boy developed recurrent abdominal pain. He was eventually discovered to have an inverted appendix via colonoscopy. At surgery, a polyploid intracecal mass was palpated at the base of the partially invaginated appendix. Resection of the cecal mass (histologically, a juvenile polyp) and appendix was easily accomplished. The types of clinical presentation and treatment of children with appendiceal intussusception are discussed.
