32 year old male with history of Crohn's disease. ABDOMEN:LIVER, BILIARY TRACT: No significant abnormality noted.SPLEEN: No significant abnormality noted.PANCREAS: No significant abnormality noted.ADRENAL GLANDS: No significant abnormality noted.KIDNEYS, URETERS: No significant abnormality noted.RETROPERITONEUM, LYMPH NODES: No significant abnormality noted.BOWEL, MESENTERY: Wall thickening and mucosal hyperenhancement are noted within the rectosigmoid colon, along an approximately 18 cm long segment which extends to the proximal anus (series 9, image 34 and series 19, image 36). Associated mesenteric hypervascularity and fibrofatty proliferation are also noted. Findings are compatible with active inflammatory bowel disease. Submucosal fat deposition in this colonic segment indicates an additional component of chronic inflammation. No free fluid, drainable collection, or fistula. The terminal ileum is not optimally assessed due to underdistention but demonstrates mucosal hyperenhancement along an approximately 9 cm segment in the right lower quadrant (series 14, image 19). BONES, SOFT TISSUES: No significant abnormality noted.OTHER: No significant abnormality noted.PELVIS:PROSTATE/SEMINAL VESICLES: No significant abnormality noted.BLADDER: No significant abnormality noted.LYMPH NODES: No significant abnormality noted.BOWEL, MESENTERY: Wall thickening and mucosal hyperenhancement are noted within the rectosigmoid colon, along an approximately 18 cm long segment which extends to the proximal anus (series 9, image 34 and series 19, image 36).

1.Wall thickening and mucosal enhancement involving an 18 cm segment of rectosigmoid colon, as well as surrounding inflammatory changes. Findings are compatible with active on chronic inflammatory bowel disease. No evidence of fistula formation or abscess. 2.Mucosal hyperenhancement along a segment of terminal ileum may also represent active disease, but evaluation in this area is limited by lack of bowel distention.
