    Brain MR imaging of case 1. Left, Initial images show faint DW imaging hyperintensities in the right temporal lobe (top) and frontoparietal junction (bottom). Right, Follow-up images obtained 6 days later show slight expansion of the DW imaging abnormalities but complete resolution of the PW imaging defects.
