Résumé
Cerebellar ataxia can be caused by neoplasia, toxics (drugs, heavy metals, alcohol), infection, vascular lesions or auto-immune and paraneoplastic pathologies. Neuroimaging must be performed urgently in case of sudden onset and serologies as well as a lumbar puncture should be performed. Several case reports of ataxia associated with COVID-19 have been published, however the underlying pathogenic mechanisms remain unclear. This is a diagnosis of exclusion when other causes are ruled out and when the ataxia appears simultaneously to COVID-19 infection. We lack data on best management, but the prognosis appears mostly favorable with good functional recovery without any specific treatment. This paper describes the case of a patient who developed a cerebellar ataxia as the only neurological manifestation of a SARS-CoV-2 infection.
