11-year-old female with history of Crohn's disease. Evaluate for perianal fistula. PELVIS:UTERUS, ADNEXA: Not well visualized.BLADDER: The bladder is distended and normal in appearance.LYMPH NODES: Small biinguinal lymph nodes are seen.BOWEL, MESENTERY: Several loops of small bowel in the pelvis demonstrate bowel wall thickening. There is equivocal bowel wall thickening of the descending colon, which could be attributed to under distention due to lack of oral contrast. Small amount of free fluid in the abdomen and pelvis.BONES, SOFT TISSUES: No perianal fistula is evident.
Several loops of distal small bowel demonstrate bowel wall thickening, consistent with given history of Crohn's disease. No perianal fistula is evident. This may be further evaluated with MR enterography, which includes oral contrast.
