1.  Jejunal Crohn's disease is frequently missed by radiologists, but is associated with worse outcomes (strictureplasties, surgeries). 2.  Jejunal Crohn's disease is characterized by asymmetric mural hyperenhancement, and wall and fold thickening. 3.  Other small bowel pathologies often cause segmental hyperenhancement or wall thickening, including neutropenic and infectious enteritis, ulcerative jejunitis in celiac disease, ACE-related visceral angioedema, vasculitis, and systemic diseases such as mastocytosis.  Examples of these entities will be shown with emphasis on unique diagnostic findings. 4.  Correlation with serum markers, and capsule and endoscopic findings often assist in the determining the cause of jejunal inflammation.

1.  Review CT/MR appearance normal jejunum in different phases of enhancment. 2.  Display numerous examples showing spectrum jejunal Crohn's disease, emphasizing key imaging findings, and  complementarity with optical imaging methods (e.g., capsule). 3.  Review treatment options for and implications of jejunal Crohn's disease. 3.  Display other pathologies causing jejunal hyperenhancement or mural thickening, with brief description and illustration of unique imaging features, as well as typical clinical history, and serologic and endoscopic findings.
