66-year-old male with ileal Crohn's disease status post ileocecectomy in 1976. ABDOMEN:LIVER, BILIARY TRACT: Scattered hepatic cysts. No suspicious hepatic lesions. No biliary ductal dilation.SPLEEN: No significant abnormality noted.PANCREAS: No significant abnormality noted.ADRENAL GLANDS: No significant abnormality noted.KIDNEYS, URETERS: Bilateral renal cysts.RETROPERITONEUM, LYMPH NODES: No significant abnormality noted.BOWEL, MESENTERY: Postsurgical changes from ileocecectomy. There is alternating narrowing and mild dilation of the terminal ileum over a length of approximately 11 cm; this segment demonstrates mild wall thickening and increased enhancement. These findings are most compatible with active on chronic inflammatory bowel disease. A skipped lesion is seen in the distal ileum with narrowing, wall thickening, and increased enhancement measuring approximately 5.5 cm in length (series 15/70), most compatible with an additional area of active inflammatory bowel disease. More proximally in the mid ileum, there are additional skipped areas of narrowing without findings suggestive of active disease.No evidence of fistula or abscess.BONES, SOFT TISSUES: No significant abnormality noted.OTHER: No significant abnormality noted.
Findings most compatible with active on chronic inflammatory bowel disease of the distal and terminal ileum as detailed above.
