Fig. 1A —73-year-old man with long-standing history of Crohn's disease who presented with abdominal pain. Patient had history of right hemicolectomy and two previous small-bowel obstructions as well as squamous cell cancer of tongue. MDCT with oral and IV contrast material administration was performed. Small-bowel series was performed next day (not shown), which showed only edematous jejunal loops but no intussusception, no mass, and no obstruction. Patient was treated conservatively, and his pain resolved. Axial image shows classic CT appearance of enteroenteric (jejunojejunal) intussusception (arrow). There was no evidence of obstruction, although small bowel was minimally dilated.
