Contribution of the virtual colonoscopy in a case of intestinal intussusception.

The present paper describes a case of ileocecal intussusception detected by ultrasound and confirmed by CT, including the imaging characteristics allowing its diagnosis. The patient was referred for colonoscopy, which could not be completed, to assess the cause of intussusception. Then it was decided to resort to Virtual colonoscopy, which allowed to identify and characterize a cecal neoplasm serving as a lead point for the intussusception.
