Post-COVID-19 vaccination magnetic resonance imaging (MRI) suggestive of encephalitis: Flair and T2 hypersignal changes in the cortical and subcortical areas of the frontoparietal lobes (a, b), cerebellar vermis, right cerebellar hemisphere and right middle cerebellar peduncle (c, d) without significant enhancement or restriction. Small focus of T1 hypersignality in the left side of the cerebellar hemisphere suggestive of hemorrhage (e). Post-treatment brain MRI (at 28 days after admission) showed subtle changes in MRI, in which signal changes disappeared (f, g, h, i, j).
