Abstract
Since the declaration of coronavirus disease 2019 (COVID-19) as a pandemic, it remains a widespread infection with a major impact on global resources and health infrastructure. The hallmark of COVID-19 continues to be the well-documented effects it has on the respiratory system. With the passage of time, the involvement of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virus in other systems has become more apparent, with the increased incidence of thromboembolic events, cardiac involvement as well as gastrointestinal and neurological symptoms secondary to the infection. Our case report demonstrates a presentation of vertigo, hearing loss, tinnitus, and aural fullness. Our patient was diagnosed as positive for COVID-19 by reverse transcription-polymerase chain reaction (RT-PCR) nine days prior to developing these symptoms. Her COVID-19 infection was otherwise relatively mild, for which she did not seek any medical intervention. A careful assessment ruled out cerebrovascular causes and led us to the diagnosis of SARS-CoV-2-induced labyrinthitis. Our patient was successfully treated as an outpatient without unnecessary investigations and responded well to standard therapy for viral labyrinthitis as per National Health Service (NHS) guidelines. She eventually reported having made a full recovery within three weeks of the initial encounter. Audio-vestibular consequences of COVID-19 are less reported compared to other symptoms of neurological involvement, such as gustatory or olfactory dysfunction, which have become key indicators aiding in the diagnosis of the infection. Among these disorders, the commonly reported presentation is that of vestibular neuronitis. Our case report demonstrates that labyrinthitis is also among the neurological manifestations to be considered as a result of COVID-19, which can be safely managed in the community with the same strategies as those employed for other viral triggers. It also reveals the need for further research into the effects that COVID-19 may have on the audio-vestibular system.
