Intussusception is primarily seen among children, most often as idiopa
thic ileocolic intussusception (1, 4), and only 5 to 16% of all intuss
usceptions are seen in adults (1, 8). In contrast to childhood invagin
ation, in adults underlying pathologic processes are identified in 18
to 90% (1, 8). This report presents 2 cases of colo-colonic intussusce
ption caused by a colonic lipoma. The ultrasonic features of this beni
gn tumour are rather characteristic. A definitive diagnosis can be pro
vided by CT.
