McSwan type V appendiceal intussusception and acute appendicitis coexistence in a 4-year-old child: a case report and review of the literature

Appendicitis, an inflammation of the appendix, and intussusception, the invagination of one intestinal segment into a distal segment, both have overlapping presentations, which can pose diagnostic and therapeutic challenges. This report describes a 4-year-old girl with coexisting McSwain type V appendiceal intussusception and appendicitis. This rare case highlights appendicitis as a potential lead point for intussusception.
