Intussusception is one of the most common @entity1661 in @entity1 , but identifying the cause is very difficult. @entity2695 is a common @entity5 of the @entity135 area in @entity1 , but it rarely arises in the gastrointestinal tract. This report describes a rare occurrence of intussusception caused by @entity8702 of the colon that was identified by ultrasonography (US), computed tomography (CT), and colonoscopy. A male @entity1 aged 2  years and 10  months developed @entity158 abdominal cramps and @entity360 . Abdominal US and CT revealed both target and pseudo-kidney signs in the colon, indicating @entity694 . An initial diagnostic and therapeutic laparotomy did not reveal any abnormalities. Seven days later, severe @entity490 recurred. A barium enema revealed the shadow of a 25-mm mass at the hepatic flexure of the colon. Colonoscopic findings revealed a @entity5 in the descending colon that was moved to the cecum by compressed air introduced through the colonoscope. We considered that the mass in the cecum had caused the intussusception. The @entity5 was removed at a second laparotomy, and microscopic pathological examination revealed that it was a @entity8702 .
