Abstract
Intussusception of the appendix (IA) is an uncommon type of intussusception with an incidence of 0.01% and an uncommon and unusual cause of ileocolic intussusception. The pediatric age group is most often affected and IA being a rare entity in adults. The IA is rarely diagnosed before surgery. Here we report on a case of IA in a 12-year-old male with ileocolic intussusception containing an inflamed appendix which was diagnosed with sonography preoperatively. An ample discussion and various classification of IA with its diagnosing and treating methods were followed.
