Phantosmia as a rare neurological manifestation in patient infected with COVID-19: A case report

Abstract

antibodies, metabolic/heavy-metal/malignancy screen, and Parkinsonism/dystonia genetic panel were negative. Given ABGApositivity and mild CSF inflammation, he received high-dose methylprednisolone and, subsequently, intravenous immunoglobulin. Myoclonus, dystonia and Parkinsonism resolved over 5-months. ConclusionsWe report the first case of COVID-19 with ABGA-positive movement disorders and CSF SARS-CoV-2 presence, without hypoxia, suggesting cerebral entry of SARS-CoV-2 could induce movement disorders by precipitating ABGA-positive autoimmune encephalitis, which improves post-immunotherapy.
