Crohn's Disease
Crohn's disease is a chronic inflammatory condition of the
intestine. The disease can be very mild or quite severe. It may
occur anywhere in the intestinal tract but most often is present
at the end of the small intestine and the colon. When the disease
is mild, the only findings may be those seen on Image 1. These
small lesions are call aphthous or target ulcers, much like ulcers
that may occur in the inside of the mouth. There is a shallow,
whitish ulcer with surrounding reddening. In Image 2, there is a
more or less diffuse reddening and inflammation, which may be
difficult to distinguish from ulcerative colitis, another chronic
inflammatory bowel disorder.
As the disease progresses, discreet white ulcers may appear as
in Image 3. These ulcers are present in the ileum, the end portion
of the small bowel. Image 4 demonstrates what happens when these
ulcers then join together, creating a great deal of whitish
ulceration, spreading across the rectum in this instance.
In severe disease, the ulcerations burrow deep into the bowel
wall creating scar formation, which can narrow the bowel as seen
in Image 5. The same type of very advanced disease is seen in
Image 6 where almost the entire bowel wall is ulcerated. These
types of lesions are difficult to heal with medicine and may
require surgery.
