title: [Intraductal biliary metastases from colorectal cancer: a report of two cases].
abstract: Intrabiliary metastases are rare, and their imaging characteristics make them easy to confuse with primary biliary tumors, especially with cholangiocarcinoma. We present two cases of patients with histories of colorectal cancer who presented with obstructive jaundice secondary to intraductal metastases. We describe the imaging findings and emphasize the key radiologic manifestations for the differential diagnosis between intrabiliary metastases and primary biliary tumors.
