We present the case of an 86-year-old man who had undergone left nephrectomy for renal cell carcinoma (clear cell carcinoma) 22 years ago. He visited the emergency department complaining of right hypochondrial pain and fever. He was eventually diagnosed with acute cholangitis. Abdominal contrast-enhanced computed tomography showed multiple tumors in the pancreas. The tumor in the pancreatic head obstructed the distal bile duct. Endoscopic retrograde cholangiopancreatography detected bloody bile juice flowing from the papilla of Vater. Therefore, he was diagnosed with hemobilia. Cholangiography showed extrinsic compression of the distal bile duct; a 6 Fr endoscopic nasobiliary drainage tube was placed. Endoscopic ultrasound showed that the pancreas contained multiple well-defined hypoechoic masses. Endoscopic ultrasound-guided fine-needle aspiration was performed using a 22 G needle. Pathological examination revealed clear cell carcinoma, and the final diagnosis was pancreatic metastasis of renal cell carcinoma (RCC) causing hemobilia. A partially covered metallic stent was placed in the distal bile duct. Consequently, hemobilia and cholangitis were resolved.
