Vestibular Neuritis Associated With COVID-19 Infection: A Case Report and Literature Review on the Time Course and Recovery

The pathophysiology of coronavirus disease 2019 (COVID-19) remains elusive, although it has been associated with symptoms such as dizziness and vertigo. Here, we report a case of vestibular neuritis following COVID-19 in a 57-year-old man who presented with rotational vertigo and dizziness exacerbated by neck rotation. The video head impulse test (vHIT) and ocular vestibular evoked myogenic potential (oVEMP) initially indicated right superior vestibular neuritis. Over a seven-month follow-up, improvements in vHIT and oVEMP were consistent with typical vestibular neuritis recovery; however, persistent postural instability and prolonged orthostatic hypotension suggested additional autonomic nervous system dysfunction. This case highlights the potential long-term vestibular impact of COVID-19.
