A. Axial FLAIR image shows ill-defined hyperintense lesions involving bilateral posterior cerebral white matter (thin arrows) and splenium of corpus callosum (thick arrow). B. Enhanced T1-weighted axial image shows no definite contrast enhancement of lesion. C. Single voxel 1H MR spectroscopy reveals increased choline peak (thick arrow). FLAIR = fluid-attenuated inversion recovery
