CHOLESTEROSIS OF THE COMMON BILE DUCT -A CASE REPORT-

Abstract

A 63-year-old woman visited to hospital complaining of discomfort of the right upper abdomen. Both ultrasonography and CT scanning showed gall stones and dilated common bile duct. ERCP revealed multiple small filling defects in the lower part of the common bile duct and endoscopic ultrasonography detected a protruding tumor in the common bile duct just above the papilla of Vater. Intraoperative cholaongioscopy revealed multiple choles-terosis of the common bile duct. Cholesterosis should be also taken into account when small mass lesions exist in the lower segment of the common bile duct.
