48-year-old man with history of Crohn's and diarrhea. ABDOMEN:LIVER, BILIARY TRACT: Punctate T2 hyperintensities are too small to actually characterize but are likely benign. Otherwise, the liver is normal in signal and morphology. The gallbladder is distended and normal. There is no intra or extrahepatic biliary ductal dilatation.SPLEEN: No significant abnormality noted.PANCREAS: The pancreatic duct is normal in caliber. No focal parenchymal lesion.ADRENAL GLANDS: No significant abnormality noted.KIDNEYS, URETERS: No hydronephrosis. No focal renal lesion.RETROPERITONEUM, LYMPH NODES: No significant retroperitoneal lymphadenopathy.BOWEL, MESENTERY: There is an approximately 16 cm length of terminal ileum with circumferential wall thickening, luminal narrowing, and enhancement (17/317). The bowel immediately proximal to this area of luminal narrowing is dilated up to 28 mm. Additionally, there are small pseudodiverticula (13/23). There is fibrofatty proliferation in the right lower quadrant containing prominent mesenteric lymph nodes.Additionally, there are loops of jejunum seen on coronal images (7/35) which are difficult to evaluate given underdistention, however these could be involved by inflammation although this is indeterminate.The colon appears normal.BONES, SOFT TISSUES: No significant abnormality noted.OTHER: No significant abnormality noted.PELVIS:PROSTATE/SEMINAL VESICLES: No significant abnormality noted.BLADDER: No significant abnormality noted.LYMPH NODES: No significant lymphadenopathy noted.BOWEL, MESENTERY: No significant abnormality noted.BONES, SOFT TISSUES: No significant abnormality noted.OTHER: No significant abnormality noted.
Terminal ileum with inflammation in the wall, luminal narrowing, proximal bowel dilation, and pseudodiverticula compatible with history of active on chronic Crohn's.
