A 78 year-old lady presented with abdominal swelling and fatigue. She was anaemic with mild hypoalbuminaemia, and had a normal alkaline phosphatase. Computed tomography showed hepatosplenomegaly and mild ascites. Anti mitochondrial antibodies were strongly positive, as were anti nuclear antibodies, and the gamma glutamyl-transferase was shown to be elevated. A diagnosis of primary biliary cirrhosis was made. A brief discussion of treatment of primary biliary cirrhosis follows. The case is notable for the fact that primary biliary cirrhosis can manifest clinically without an elevation in alkaline phosphatase - normally the hallmark of the disease.
