History of Crohn's disease with high ostomy output The study is limited secondary to motion artifact.ABDOMEN:LIVER, BILIARY TRACT: 9 mm segment 6 liver cyst is unchanged. No suspicious liver lesion is identified. No biliary duct dilation.SPLEEN: No significant abnormality noted.PANCREAS: No significant abnormality noted.ADRENAL GLANDS: No significant abnormality noted.KIDNEYS, URETERS: No significant abnormality noted.RETROPERITONEUM, LYMPH NODES: No significant abnormality noted.BOWEL, MESENTERY: Right lower quadrant ileostomy is seen in place. Status post sigmoid resection, small bowel resection, and ileocecectomy. No definite bowel wall thickening or dilated bowel loops are seen. BONES, SOFT TISSUES: T2 hyperintense, nonenhancing, diffusion restricting lesions in the left paracolic gutter likely represents abscesses (favored over collapsed laterally displaced small bowel loops). The largest of the abscesses measures 2.5 x 1.0 cm (image 66, series 2601). A network of sinus tracts is seen connecting the abscesses with stellate appearance noted and there is also fistulous communication to the residual rectum. There is surrounding edema and inflammation extending into the adjacent left iliacus muscle. These findings are new compared to the prior CT of 12/4/2014.PELVIS:UTERUS, ADNEXA: No significant abnormality noted.BLADDER: No significant abnormality noted.BOWEL, MESENTERY: No significant abnormality noted.BONES, SOFT TISSUES: Left paracolic gutter abscesses and sinus tracts as described above.
1.Limited exam secondary to motion artifact.2.Left paracolic gutter abscesses and sinus tracts with fistulous communication with the rectal stump. 3.No definite evidence of enteritis.
