24-year-old male patient with history of Crohn's disease. Evaluate extent of disease and evaluate for small bowel disorder. 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: Subcentimeter left renal cyst.RETROPERITONEUM, LYMPH NODES: No significant abnormality noted.BOWEL, MESENTERY: There is bowel wall thickening, increased T2 signal, pericolonic edema, and hyperenhancement of a 20 cm segment of colon from the splenic flexure to the sigmoid colon. There is narrowing of the bowel caliber in this segment with loss of normal bowel features. At the transition to normal bowel, there is focal narrowing (series 5 image 21). In this area there is thickening of the adjacent abdominal wall and increased T2 signal, which may represent postoperative changes versus a sinus tract.There is mild bowel wall thickening, increased T2 signal, and enhancement of the distal 10 cm of rectosigmoid colon.The terminal ileum is within normal limits. No evidence of small bowelBONES, SOFT TISSUES: No significant abnormality noted.OTHER: No significant abnormality noted.
1.Findings compatible with acute on chronic inflammation in a segment of the descending colon with focal narrowing as described above, compatible with history of Crohn's disease.2.Mild rectosigmoid inflammatory changes.3.No evidence of small bowel involvement.4.Thickening of the abdominal wall and increased T2 signal adjacent to the focal narrowing in the sigmoid colon may represent postoperative changes versus a sinus tract.
