Crohn's disease presenting as isolated jejunitis years after childhood colitis

We present a case of a patient who had documented ulcerative colitis as a child and later presented with isolated Crohn's jejunitis. Although rare, Crohn's disease must be considered in those patients with segmental inflammation of the small bowel and a prior history of inflammatory bowel disease involving the colon. Patients with colitis that do not show specific criteria for either ulcerative colitis or Crohn's disease should be classified as indeterminant colitis, and a small bowel series is indicated. It may be indicated to obtain a small bowel series in patients with any form of colonic inflammatory bowel disease, periodically, after diagnosis.
