title: [A case report of renal cell carcinoma with metastatic intraductal tumor thrombus of the common bile duct].
abstract: We present a case of liver metastasis of renal cell carcinoma (RCC) presenting as an intraductal tumor thrombus of the common bile duct. A 62-year-old man was admitted with jaundice. He had undergone right nephrectomy for RCC 8 years previously, and had been administered interferon alfa for lung, bone, and liver metastases for these 3 years. Abdominal enhanced computerized tomography (CT) disclosed the progression of liver metastasis to the common bile duct and the dilated bilateral bile ducts. Endoscopic retrograde cholangiopancreatography (ERCP) revealed a smooth filling defect in an upper portion of the common bile duct, suggesting an intraductal RCC tumor thrombus of the common bile duct. He died 4 months later despite the percutaneous biliary drainage. Liver metastasis of RCC proceeding to the common bile duct is extremely rare, and this is the 8th case. We should be aware of the fact that metastatic intraductal tumor thrombus of the common bile duct can cause obstructive jaundice.
