A fatal case of COVID-19-associated acute necrotizing encephalopathy.

A variety of COVID-19 neurological manifestations have been reported to date, including various forms of encephalitis and encephalopathy. In our patient, encephalopathy with seizures was the presenting symptom of SARS-CoV-2 infection. The radiological findings on days 8 and 9 were consistent with an ANE. The precise pathogenesis of ANE remains unclear; however, an immune-mediated mechanism is suspected. Early diagnostics with prompt administration of immunomodulators may be lifesaving. Suspicion of a COVID-19-related encephalopathy/encephalitis should be raised in all patients with altered mental status, seizures, and/or coma.
