A Woman with Recent Jaundice and Pruritus

A middle-aged woman suffering from jaundice and pruritus that had begun a month previously was presented to a physician.At the first assessment, laboratory findings had revealed a cholestatic pattern and serologic tests for hepatitis B virus (HBV), hepatitis C virus (HCV) and hepatitis A virus (HAV) were negative. Normal findings of abdominal computed tomography (CT) scan and endoscopic retrograde cholangiopancreatography (ERCP) ruled out extrahepatic causes of cholestasis. A liver biopsy was done and showed intrahepatic cholestasis without destruction of the bile ducts or granuloma.We assessed the intrahepatic causes of cholestasis. Finally the diagnosis was confirmed by means of a simple test.
