An elongated solid lesion observed on ultrasonography and CT in the biliary tree causing a smooth filling defect on cholangiography was observed in 2 patients. No tumor was observed in the liver parenchyma either on radiography or at operation. Histopathology showed hepatocellular carcinoma. After removal of the intraductal tumors, recurrence was observed in 2 and 6 months, respectively.
