A case of acquired hepatocerebral degeneration with prominent improvement of parkinsonism and cognitive deficits after living-donor liver transplantation

Abstract

A 53-year-old woman visited us for a neurological consultation before her liver transplantation. She had a history of primary biliary cirrhosis that began at 37 years of age. She showed falling episodes and met with a traffic accident at 52 years old. Since then, her symptoms had worsened. The neurological examination showed masked face, rigidity on bilateral arms and legs, and lack of balance. Her Mini-Mental State Examination Score was 28/30, but she suffered from loss of memory and had trouble with executive function in detailed examinations. Her T₁ weighted image showed hyperintensity in bilateral globus pallidus, putamen, dentate nucleus and cerebral peduncle. There was a significant improvement in intellectual function and neurological signs 6 months after her orthotopic liver transplantation. In addition, post-liver transplantation images showed a decrease in the area of hyperintensities. This case suggests that even in a patient with severe liver cirrhosis a complete cure of neurological manifestations can be obtained after the liver transplantation.
