History of primary sclerosing cholangitis and ulcerative colitis. Evaluate for dominant stricture. ABDOMEN:LIVER, BILIARY TRACT: The liver is normal in morphology and signal intensity.Demonstrated again is multifocal narrowing and mild prominence/ectasia of the biliary tree not significantly changed from the prior study. There is a long segment 2.5 cm stricture of the left hepatic duct (series 10/1), similar to the prior study without associated abnormal enhancement. Similar stricturing affects the more central right and left hepatic ducts. No abnormal postcontrast enhancement or suspicious liver lesion.Note is made of an enhancing plaque-like lesion in the gallbladder fundus which is slightly increased from the prior study (series 13/53) measuring 1.9 cm.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: No significant abnormality noted.BONES, SOFT TISSUES: Small fat-containing umbilical hernia.OTHER: No significant abnormality noted.
1.Mild progression of irregular narrowing and dilatation of the right and left intrahepatic biliary ducts without a new dominant stricture or discrete mass.2.Increasing size of a plaque-like mucosal lesion of the gallbladder fundus. The lesion does not have the typical features of adenomyomatosis.
