Colitis

Colitis, or inflammation of the colon, is a frequent cause of abdominal pain. Specific entities which produce inflammatory thickening of the colon include diverticulitis, inflammatory bowel disease, pseudomembranous colitis, and other bacterial infections (i.e. typhlitis). It is important to remember that other common etiologies such as adenocarcinoma and ischemia can also produce bowel wall thickening.
