Abstract

Epstein-Barr virus (EBV) causes a variety of central nervous system infections, including encephalitis. EBV encephalitis accounts for approximately 5.8% of all viral encephalitis, with fever, headache, convulsions, and decreased consciousness as common symptoms. Brain magnetic resonance imaging (MRI) in EBV encephalitis shows high signal intensity mainly in the parieto-occipital cortex, subcortical white matter, and deep gray matter nuclei with reversibility. In this report, we present a case of bilateral corticospinal tract involvement (wine glass sign) identified on brain MRI in a patient with diagnosed with EBV encephalitis.
