Colo-Colonic Intussusception Caused by Lipoma

Intussusception is primarily seen among children, most often as idiopathic ileocolic intussusception (1, 4), and only 5 to 16% of all intussusceptions are seen in adults (1, 8). In contrast to childhood invagination, in adults underlying pathologic processes are identified in 18 to 90% (1, 8). This report presents 2 cases of colo-colonic intussusception caused by a colonic lipoma. The ultrasonic features of this benign tumour are rather characteristic. A definitive diagnosis can be provided by CT.
