71-year-old female with history of radiation for anal cancer, prior small bowel obstruction status post small bowel resection, with diarrhea and weight loss. ABDOMEN:LIVER, BILIARY TRACT: No significant abnormality noted.SPLEEN: No significant abnormality noted.PANCREAS: No significant abnormality noted.ADRENAL GLANDS: No significant abnormality noted.KIDNEYS, URETERS: Nonenhancing T2 hyperintense focus of the right interpolar region is too small to characterize, favor cystic. No hydronephrosis.RETROPERITONEUM, LYMPH NODES: No significant abnormality noted.BOWEL, MESENTERY: No bowel obstruction or ascites. Above average stool burden compatible with constipation.The terminal ileum demonstrates a short segment of mild wall thickening and hyperenhancement on postcontrast series (axial series 22 image 35). No upstream dilatation. No evidence for other stricture or fistulization.There is suspected just under distention of small bowel loops in the left mid hemiabdomen at the level of the umbilicus (axial series 11 image 17). Improved distention was visualized as the study progressed. On the postcontrast series, there is no significant wall thickening or hyperenhancement (axial series 22 image 27).BONES, SOFT TISSUES: No significant abnormality noted.OTHER: No significant abnormality noted.PELVIS:UTERUS, ADNEXA: Uterus is atrophic versus surgically absent.BLADDER: No significant abnormality noted.LYMPH NODES: No significant abnormality noted.BOWEL, MESENTERY: As above.BONES, SOFT TISSUES: Restricted diffusion of the right hemisacrum and left posterior iliac bone likely related to prior radiation change (axial series 13 images 22, 24).OTHER: No significant abnormality noted.
1.Short segment wall thickening and hyperenhancement of the terminal ileum with no upstream dilatation. Findings compatible with mild terminal ileitis, of uncertain etiology. No additional signs of Crohn's disease, i.e., no fibrofatty proliferation or locoregional adenopathy seen.2.Above average stool burden consistent with constipation.3.Restricted diffusion of the right hemisacrum and left posterior iliac bone presumably related to prior radiation change, correlation with patient's clinical history recommended.
