Computed Tomography of Entero-Enteric Intussusception

Abstract
Characteristic computed tomographic findings of entero-enteric intussusception were demonstrated with in vitro studies of surgically created intussusceptions in canine small bowel. The signs were effective in detecting intussusception in 2 patients, 1 with metastatic melanoma and a 2nd with a plasmacytoma, both of whom had previously nondiagnostic standard oral contrast medium examinations. The findings consist of a dilated loop of bowel (the intussuscipiens) with a thickened wall, within which is an eccentric soft tissue mass (the intussusceptum) and an adjacent crescentic low density mass on the mesenteric side, representing the invaginated mesentery.
