Quiz Case Magnetic Resonance Cholangiopancreatography in the Diagnosis of Choledocholithiasis

摘要

A 55-year-old man presented with nausea, vomiting, and abdominal pain. Laboratory tests revealed a total bilirubin of 1.7 mg/dL (normal range 1.0-1.2), alkaline phosphatase 194 U/L (normal range 35-125), ALT 591 U/L (normal range 21-72), and AST 304 U/L (normal range 17-59). Sonography showed cholelithiasis and a common bile duct diameter of 6 mm without evidence of Choledocholithiasis. MRI with magnetic resonance Cholangiopancreatography (MRCP) was performed 10 days later to evaluate persistent symptomatology (Fig. 1).
