Ileo-colic intussusception by ileo-cecal valve lipoma – an infrequent ultrasonographic occurrence. A case report.

Abstract

We present a rare cause of intestinal obstruction in an adult, due to ileo-colic intussusception by a lipoma of the ileo-cecal valve and its ultrasonographic presentation. The case presented in emergency for spontaneously appearing and disappearing palpable elastic mass in the right iliac fossa. The ultrasonographic examination raised the suspicion of an ileo-colic intussusception due to a polypoid tumor. The contrast-enhanced computed tomography confirmed the finding and suggested that the polypoid tumor was more likely a lipoma. Right hemicolectomy and cholecystectomy were performed and the pathological examination confirmed the lipoma. The evolution of the patient was favourable and uneventful.
