SARS-CoV-2-associated encephalitis: a case report

Abstract

COVID-19 presents with respiratory symptoms and signs in the majority of cases. The central nervous system can be affected directly or indirectly, which is demonstrated by a number of neurological abnormalities and complications. The aim of this study is to present a clinical case of SARS-CoV-2-associated encephalitis and highlight the severity of this neurological illness over the course of COVID-19. Etiological diagnosis methods include examination of the nasopharyngeal swab and cerebrospinal fluid by PCR. A 45-year-old man with fever, altered consciousness, and tonic-clonic seizures was admitted to the Clinic of Infectious Diseases, St George University Hospital, Plovdiv. The diagnosis of COVID-19 encephalitis is based on typical clinical and laboratory data, positive SARS-CoV-2 PCR, and exclusion of other likely causative agents into the cerebrospinal fluid. The patient was discharged two weeks after admission without neurological sequelae. The case confirms the clinical variety of COVID-19 and the possibility of severe neurological manifestations. Encephalitis is a rare but potentially life-threatening condition. Physicians should be aware of encephalitis in SARS-CoV-2 patients with neurological symptoms.
