[Computed tomographic diagnosis of an ileocolic invagination in an adult].

Intussusception is an uncommon cause of intestinal obstruction in adults. Unlike children, the diagnosis of intussusception in adults is often difficult due to its usually chronic history. A case of adult ileocolic intussusception secondary to metastatic melanoma is presented to discuss the efficiency of ultrasonography, characteristic CT features and the etiology of this disease.
