History of Crohn's disease with persistent perirectal fistula on recent MRI, evaluate disease status.EXAMINATION: MR enterography without and with IV contrast 12/15/2015 ABDOMEN:LIVER, BILIARY TRACT: The liver demonstrates normal parenchymal signal intensity without focal lesions.SPLEEN: No significant abnormality noted.PANCREAS: No significant abnormality noted.ADRENAL GLANDS: No significant abnormality noted.KIDNEYS, URETERS: The kidneys demonstrate normal enhancement and excretion. No hydronephrosis.RETROPERITONEUM, LYMPH NODES: No significant abnormality noted.BOWEL, MESENTERY: There is an approximately 15 cm segment of distal ileum extending to the ileocecal valve with mild wall thickening, hyperenhancement, restricted diffusion, and mild luminal narrowing. This segment is relatively adynamic on cine sequences. Overall, these changes are slightly less prominent and involve a shorter segment of bowel compared to the 12/16/2014 examination. There is no associated high-grade bowel obstruction. No intra-abdominal fluid collection is present.BONES, SOFT TISSUES: No significant abnormality noted.OTHER: No significant abnormality noted.PELVIS:PROSTATE, SEMINAL VESICLES: No significant abnormality notedBLADDER: No significant abnormality notedLYMPH NODES: No significant abnormality notedBOWEL, MESENTERY: There is an approximately 15 cm segment of distal ileum extending to the ileocecal valve with mild wall thickening, hyperenhancement, restricted diffusion, and mild luminal narrowing.

1.Active inflammatory changes involving approximately 15 cm segment of distal ileum compatible with Crohn's disease overall slightly less prominent than 12/16/2014 examination.2.Recently described perianal fistula is incompletely visualized and better evaluated on 12/14/2015 dedicated pelvic MRI.
