|Text||It is well known that Crohn's disease can effect any portion of the GI tract, however, the terminal ileum and proximal colon are the two most common sites of involvement (1). CT features of Crohn's disease include bowel wall thickening, vascular engorgement of the mesenteric vessels, and prominent spacing between vessels from fibrofatty proliferation (creeping fat)(1,2). The presence of skip lesions with normal intervening mucosa, sinus tracts and/or fistula formation are other associated findings.
Complications of Crohn's disease include small bowel obstruction and abdominal abscess (3).
