History of Crohn's disease. Evaluate for evidence of active inflammation. 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: The small bowel is adequately distended with oral contrast. The small bowel fold pattern is maintained. The terminal ileum is well seen and demonstrates no significant active inflammation. There are intermittent regions of jejunal underdistention likely related to peristalsis without specific evidence of active inflammation. No flow-limiting stricture.The descending colon is featureless. Starting at the splenic flexure the colon demonstrates mild to moderate regions of long-segment mild T2-weighted hyperintensity, restricted diffusion and post-contrast enhancement compatible with active inflammation. This is most severe at the sigmoid colon. At the level of the rectosigmoid is a short segment skip region with subsequent short segment skip lesion. The distal rectum appears spared. Proximal to the splenic flexure I suspect regions of intermittent peristaltic contraction (see dynamic images) but no flow-limiting stricture or definite evidence of active inflammation. There is engorgement of the pericolonic vasa recta and scattered small reactive lymph nodes. There is no significant upstream dilatation to suggest a flow-limiting stricture.No evidence of sinus tract or fistula formation. No free fluid or loculated fluid collection.BONES, SOFT TISSUES: No significant abnormality noted.OTHER: No significant abnormality noted.PELVIS:UTERUS, ADNEXA: No significant abnormality noted.BLADDER: No significant abnormality noted.LYMPH NODES: No significant abnormality noted.BOWEL, MESENTERY: The descending colon is featureless.

No significant active inflammation of the small bowel. Moderate active inflammation of a featureless distal colon from the splenic flexure extending distally with short skip areas near the rectosigmoid and distal rectum. The inflammation is most severe of the sigmoid colon. No flow-limiting stricture or evidence of sinus tract/fistula formation.
