Computed tomography of Crohn’s disease: The role of three dimensional technique

Figure 6 Abscesses related to Crohn’s disease. A: Forty-three-year-old female with Crohn’s disease. Coronal and sagittal computed tomography images with contrast demonstrate a right-sided perianal rim-enhancing fluid collection/abscess (A1 and A2, arrows) with a direct tract extending from the abscess to the rectum; B: Thirty-six-year-old male with Crohn’s disease. Coronal contrast-enhanced image demonstrates a thickened loop of ileum in the right lower quadrant with marked adjacent phlegmonous change and inflammation, as well as an abscess (arrow) along the mesenteric border of the inflamed loop of bowel.
