Case Discussion
Crohn's disease is an idiopathic inflammatory bowel disease (IBD), characterized by widespread discontinuous gastrointestinal tract inflammation. The terminal ileum and proximal colon are most often affected. The comb sign refers to the hypervascular appearance of the mesentery in active Crohn's disease.
