During patient's first attack of MOG cortical encephalitis, MRI brain showed restricted diffusion (A) with ADC correlate (B), FLAIR hyperintensity (C, D) involving the cortex in the right posterior temporal and parieto-occipital lobes with associated focal leptomeningeal enhancement (E, F), and bilateral non-enhancing FLAIR (C) hyperintense thalamic lesions with restricted diffusion (A).

Brain MRI with and without gadolinium showed T2/FLAIR hyperintensity and restricted diffusion involving the cortex in the right posterior temporal and parieto-occipital lobes with associated focal leptomeningeal enhancement as well as a non-enhancing bilateral thalamic T2/FLAIR hyperintense lesions (Figure 1).
During patient's second attack of MOG cortical encephalitis, MRI brain showed complete resolution of previous right hemispheric abnormalities with development of left posterior temporal-parietal FLAIR abnormalities (A, arrow) with associated leptomeningeal enhancement (B, arrow).
