|Axial T2 FLAIR images showing diffuse hypointensity of bilateral frontoparietal white matter with sparing of subcortical U fibres. There is sparing of perivascular white matter giving a "TIGROID" or "LEOPARD SKIN" appearance|
|Axial and Sagittal T2 Wt images show extent of hyperintense signal in bilateral fronto temporo parieto occipital white matter from deep periventricular region to subcortical region |
with sparing of U fibres.
|Axial DWI and sagittal T1 Wt images: Mild restricted diffusion noted along the advancing edge of dysmyelination. Note the involvement of distal body and splenium of corpus callosum |
in the disease process on T1 Wt image.
