title: Inflammatory pseudotumor from sclerosing cholangitis.
abstract: We report the computed tomographic (CT) findings in a case of primary sclerosing cholangitis. A "mass" demonstrated on CT and ultrasound examination in the region of the common bile duct and extending into the head of the pancreas was shown to be diffuse fibrosis and thickening of the common bile duct at surgery.
