History of ulcerative colitis status post total proctocolectomy and ileal pouch anal anastomosis presenting with loose stools and ulcers in the pouch. History of PSC. ABDOMEN: Susceptibility artifact from the IVC stent severely limits multiple image sequences.LIVER, BILIARY TRACT: Limited evaluation of the liver due to susceptibility artifact.SPLEEN: No significant abnormality noted.PANCREAS: No significant abnormality noted.ADRENAL GLANDS: No significant abnormality noted.KIDNEYS, URETERS: Note is made of mild right-sided pelvocaliectasis and mild dilatation of the proximal ureter, increased from the prior study. The mid ureter is collapsed and mildly thickened, uncertain in etiology and may be post surgical. T2 hyperintense renal foci, likely cysts.RETROPERITONEUM, LYMPH NODES: No significant abnormality noted.BOWEL, MESENTERY: Postsurgical changes from total proctocolectomy with ileal pouch anal anastomosis.There is mildly T2 hyperintense wall thickening and hyperenhancement of the ileal pouch with surrounding fibrofatty proliferation and small lymph nodes compatible with active inflammation. Proximal to the ileal pouch there are several short segment discontinuous thickened and narrowed bowel loops including a 7.5 cm narrowed bowel loop in the mid abdomen (series 5/26) without associated upstream dilatation. Additional short segment skip lesion (series 3/21).No free fluid or loculated fluid collection. No evidence of bowel obstruction.BONES, SOFT TISSUES: No significant abnormality noted.OTHER: No significant abnormality noted.
1.Severely limited evaluation of the upper abdomen due to susceptibility artifact from the IVC stent.2.Findings suggesting moderate pouchitis and multiple skip lesions involving the distal ileum. No evidence of flow-limiting stricture or drainable fluid collection.3.New mild right-sided pelvocaliectasis with mid right ureter thickening and narrowing of uncertain etiology. This may be post surgical.
