MR demonstrates diffuse right cerebral hemiatrophy with encephalomalacia and gliotic changes involving the whole hemisphere. There is also severe ex vacuo dilatation of the right lateral ventricle. Reduction in volume of the ipsilateral cerebral peduncle due to Wallerian degeneration.
There is also contralateral cerebellar hemiatrophy and gliosis with atrophy of the left middle cerebellar peduncle was noted.
