Hearing Loss and Sixth Cranial Nerve Paresis after COVID-19

An 80-year-old patient was admitted to the internal medicine department for binocular diplopia and hearing loss with sudden onset. The patient had presented with SARS-CoV-2 infection 3 weeks previously and had been admitted to hospital. Complete work-up including autoimmunity, serum and LCR viral serology and MRI did not allow a diagnosis to be established. The hypothesis of a microvascular origin or the previous SARS-CoV-2 infection was considered. The latter was retained in light of the temporal relationship, the absence of other pathologies after exhaustive work-up, and the clinical evolution. LEARNING POINTS: A temporal relationship between SARS-CoV-2 infection and symptoms in the absence of other pathologies is important for diagnosis. Mid or long-term follow-up is necessary in patients with unexplained symptoms after SARS-CoV-2 infection.
