  • mural thickening and contrast enhancement of the mucosa of the ileal loops and terminal ileum

  • prominent peri enteric vasculature of the mesentery

  • vascular dilatation and tortuosity of the vasa recta, giving the comb sign

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.
