[Computed tomographic aspects of intestinal intussusception].

This article describes typical CT findings of intestinal intussusception of different genesis and localisation. It is shown that a characteristic image resembling a target is obtained both in case of an invaginated Meckel's diverticulum, an idiopathic ileocolic intussusception in an infant, and in colorectal invagination in condition after resection of a polyp of the sigmoid. Compared with the conventional imaging methods such as sonography, colon contrast enema or contrast imaging of the small intestine, CT enables not only unequivocal diagnosis of intestinal invagination but frequently also the identification or exclusion of underlying causes that trigger the phenomenon.
