We report a 13-year-old girl who presented with hepatic failure and hemolytic anemia. Laboratory findings showed a normal serum copper level (104 microg/dl), high urinary copper level (2370 microg/dl), and low serum ceruloplasmin level (14.3 microg/dl). Slit-lamp examination revealed Kayser-Fleischer rings on her cornea, and she was diagnosed with Wilson's disease. Plasma exchange and continuous hemodiafiltration relieved the serious condition, after that laparoscopic examination was performed. Administration of D-penicillamine and restriction of dietary copper (<1 mg/day) were started, leading to a normalized serum alanine amino transferase (ALT) level. After 3 years, she again underwent laparoscopic examination, and the laparoscopic and histological findings of her liver were obviously improved. Management of the copper level can reverse severe liver fibrosis in Wilson's disease.
