    Fig 1.

    Axial FLAIR image with fat saturation (A) and a turbo spin-echo T2-weighted image (B). There are confluent and strikingly symmetric signal-intensity abnormalities in the white matter of both cerebral hemispheres, with sparing of the subcortical U-fibers. The posterior fossa structures are normal.

    Fig 2.

    Proton single-voxel MR spectroscopy, performed with a TE value of 270 ms. There is a striking decrease of the NAA peak with a relative increase of the choline peak. A lactate peak with a resonance frequency at 1.32 ppm is present and shows a characteristic “up” doublet configuration.
