C.A.T. in Leukodystrophy and Neuronal Degeneration

Conventional neuroradiology previously had a limited part to play in distinguishing the diseases grouped under the generic terms leukodystrophy and neuronal degeneration from tumours when the clinical presentation was atypical. Atrophy may occur in any of these conditions and its distribution is sufficiently distinctive to allow recognition of, for example, striatonigral and pontocerebellar degeneration and of progressive supranuclear palsy on pneumoencephalograms.
