A 60s-year-old man was admitted to our hospital with cholangitis and obstructive jaundice. CT revealed a mass with an unclear border that occupied almost the entire left lobe of the liver and solid components in the hilar bile duct. There was a mass in the hilar bile duct by direct cholangioscope. Total colonoscopy revealed mass in the descending colon. The patient was diagnosed with colorectal cancer and intrahepatic cholangiocarcinoma. We performed left hemicolectomy, left hepatectomy, caudate lobectomy, and extrahepatic bile duct resection. The cut surface of the resected specimen showed a tumor thrombi filling the entire bile duct and protruded into the hilar bile duct. Histopathological findings were similar to those of colorectal cancer lesions. Immunostaining was negative for CK-7 and positive for CK-20. The lesion was diagnosed as liver metastasis of the colorectal cancer.
