We report the case of a 68-year-old woman who had abdominal pain and slightly elevated biliary enzymes. Magnetic resonance cholangiopancreatography detected biliary duct stenosis, while contrast-enhanced magnetic resonance imaging showed that the right hepatic artery transversed the extrahepatic bile duct at the level of bifurcation of the bile duct. We performed endoscopic retrograde cholangiopancreatography and peroral cholangioscopy with the SpyGlass DS™ system. Then, mild extrinsic pulsatile compression of the bile duct was observed at stricture level with an intact bile duct epithelium. Therefore, she was diagnosed with right hepatic artery syndrome and underwent cholecystectomy. Six months later, her biliary enzyme level decreased, and the recurrence of pain gradually decreased.
