History of perianal fistula. Evaluate for evidence of Crohn's disease. ABDOMEN:LIVER, BILIARY TRACT: The liver dome is not included in the field of view. The visualized portions of the liver are normal without focal lesion biliary ductal dilatation or vascular abnormality. Normally distended gallbladder without cholelithiasis.SPLEEN: Normal splenic size and morphology without focal lesion.PANCREAS: No significant abnormality noted.ADRENAL GLANDS: No significant abnormality noted.KIDNEYS, URETERS: Partially duplicated right renal collecting system with fusion of the ureters at the mid abdomen. No hydronephrosis. No focal suspicious lesion.RETROPERITONEUM, LYMPH NODES: No significant abnormality noted.BOWEL, MESENTERY: The small bowel is well-distended with oral contrast. There is no wall thickening, abnormal enhancement or adjacent inflammatory changes. The terminal ileum is well seen and is normal in appearance. No fluid collections. No focal persistent stricture is evident. Portions of the colon are underdistended limiting evaluation for bowel wall thickening which is not suspected. No abnormal postcontrast enhancement of the colonic wall.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: No significant abnormality noted.BONES, SOFT TISSUES: Postcontrast images were not performed of the perineal soft tissues limiting evaluation. There is a fistulous tract extending from approximately the 12:00 location of the anal canal which progresses inferiorly and extends to the left gluteal cleft. No associated fluid collection. No evidence of extension through the outer sphincter.OTHER: No significant abnormality noted.
