Autoimmune Hepatitis or Wilson’s Disease, a Clinical Dilemma

The etiologic diagnosis of acute hepatitis and the correct therapeutic strategy may sometimes present several difficulties. We report the case of a young male patient with a severe acute hepatitis resembling features of both autoimmune hepatitis (AIH) and Wilson disease (WD). A 32-year old man presented with a seven days history of fatigue, low-grade fever and jaundice. The patient did not use tobacco, alcohol or illicit drugs. His parents and two siblings were in good health. Clinical examination revealed body temperature 37 ºC, blood pressure 130/80 mmHg, heart rate 72 beats/min and respiratory rate 20/ min.
