Abstract
Three cases of cholangiocarcinoma associated with intrahepatic cholelithiasis were reported. One case did not undergo resection, two cases had curative resections. These cases were diffcult to make a differential diagnosis from chronic cholangitis, liver abscess. US-guided liver biopsy was the most useful procedure to make a preoperative diagnosis of chlangiocarcinoma associated with intrahepatic cholelithiasis.
