Intussusception of the appendix.
Four new cases of appendiceal intussusception are reported bringing the total of reported cases to about 150. The correct diagnosis is rarely made either in acute or chronic cases. If the diagnosis is made intraoperatively, unnecessary right colon resection can be avoided as appendectomy with a small margin of cecal wall is all that is indicated.
