Which of the following differentiates ulcerative colitis from Crohn’s disease?
A- Crohn’s disease primarily affects the left colon and rectum and ulcerative colitis most often affects the right colon and distal ileum.
B- Crohn’s disease presents with shallow ulcerations and ulcerative colitis presents with a cobblestone appearance of the mucosal lining.
C- The extent of involvement is noncontiguous and segmented with Crohn’s disease and it is contiguous and diffuse with ulcerative colitis.
D- Crohn’s disease has primarily mucosal involvement and it is transmural with ulcerative colitis.
Correct Response: C
The extent of involvement is noncontiguous and segmented with Crohn’s disease; and it is contiguous and diffuse with ulcerative colitis. Other differentiating characteristics include:
The typical area of intestinal involvement is the left colon and rectum for ulcerative colitis and the right colon and distal ileum with Crohn’s disease.
The mucosal appearance has a cobblestone appearance with granulomas with Crohn’s disease; and it appears edematous with shallow ulcerations and superficial bleeding.
The inflammation associated with Crohn’s disease is transmural, and it is mostly mucosal among those with ulcerative colitis.
