[Acute hemolytic crisis followed by fulminant hepatic failure with fatal outcome, as a first clinical manifestation of Wilson's disease]. / Crise hemolítica aguda seguida por insuficiência hepática fulminante com evolução fatal, como primeira manifestação clínica da doença de Wilson.

We describe in this work a clinical case of a female patient aged 21 years, bearer of Wilson's disease, a first clinical manifestation of the disease occurred as an acute hemolytic crisis followed by fulminant hepatic failure evolving to death after 26 days' internment. The definitive diagnosis was obtained only as a quantitative measurement of hepatic copper from the necropsy material. The search for Kayser-Fleischer ring was negative and the serum ceruloplasmin level was 9 mg/dl (15 to 60). No involvement of the central nervous system was noted from the pathologic analysis. The patient presented two Coombs negative hemolytic crises during the internment; the first on being admitted to hospital and the second after a transjugular hepatic biopsy carried out on the 16th day after internment. The last hemolytic crisis was accompanied by an increase of serum and urinary copper levels. On this occasion the patient evolved to a progressive hepatic failure with severe jaundice and hepatic encephalopathy. We are presenting the clinical-biochemical evolution of the patient and we shall discuss the existent hypotheses to the pathophysiology of this rare form for manifestation of the Wilson's disease as well the diagnostic difficulties.
