Abstract
Background: There are growing reports of the neurological involvement among patients with coronavirus disease 2019 (COVID-19). Headache, confusion, and anosmia after olfactory nerve disruption are the most prevalent presentation of the neurological involvement related to COVID-19. However, small numbers of the central nervous system involvement have been reported.
Case report: A 49-year-old man was referred to our hospital with abrupt vision loss. Three weeks earlier he was admitted to the hospital based on his respiratory symptoms and was diagnosed with COVID-19 infection. Initial brain magnetic resonance imaging indicated diffuse restricted bilateral foci in both parietal and occipital lobes in favor of acute infarction. Diffuse weighted imaging demonstrated restricted bilateral hyperintense signals in parietal and occipital region. Occipital cortex biopsy showed brain tissue with focal infiltration of foamy macrophages mixed with reactive astrocytes and no plasma cell infiltration. Considering all of the evidence, post-COVID-19 encephalitis diagnosis was considered for the patient, and methyl prednisolone pulse therapy and intravenous immunoglobulin were initiated. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Although there are growing reports of neurological involvement among patients, blindness is rarely observed as a complication of post-COVID-19 encephalitis. To our knowledge, this is the first case of post-COVID-19 encephalitis that presented with bilateral vision loss primarily. This case may raise physicians' awareness of neurological complications of COVID-19.
