Transient Generalized Chorea in Influenza A Encephalopathy

Tremor Other Hyperkinet Mov (N Y). 2018 Oct 9:8:591. doi: 10.7916/D8F495TP. eCollection 2018.

Abstract

Background: Influenza A infections are a rare cause of movement disorders. Previously described patients have suffered from acute-onset myoclonus and/or dystonia or post-viral parkinsonism.

Case report: We present the case of a 74-year-old female patient with transient generalized chorea due to influenza A-mediated encephalopathy.

Discussion: We discuss whether the clinical presentation and the magnetic resonance imaging changes may be attributable to cytokine-mediated encephalopathy or to direct cytotoxic effects of the virus. Additionally, we would like to make clinicians aware of this clinical sign in the context of viral encephalopathy.

Keywords: Influenza; chorea; diffusion-weighted imaging lesion; encephalopathy.
