A repeat brain MRI done at this time (one year after onset of illness) showed marked improvement with complete resolution of the some of the cortical lesions in the parietal and occipital regions bilaterally and residual hyperintensity in the periventricular and supraventricular cerebral white matter bilaterally involving the parieto-occipital regions predominantly; there were no new lesions (Figure 4, Figure 5, Figure 6).
(MRI post treatment) is T1 w midsagittal sequence showing complete resolution of the lesion seen in the pretreatment midsagittal image
