“…It might be difficult to differentiate extrapontine myelinolysis from Wallerian degeneration [24]. In fact, several case reports of pontine stroke present with signal abnormalities in the middle cerebellar peduncles [25]. However, in Wallerian degeneration signal abnormalities are usually fainter compared with those of extrapontine myelinolysis.…”

Apparent diffusion coefficient restriction in the white matter: going beyond acute brain territorial ischemia

et al. 2011

BackgroundReduction of apparent diffusion coefficient (ADC) values in white matter is not always ischaemic in nature.MethodsWe retrospectively analysed our MRI records featuring reduced ADC values in the centrum semiovale without grey matter involvement or significant vasogenic oedema.ResultsSeveral conditions showed the aforementioned MR findings: moose-horn lesions on coronal images in X-linked Charcot-Marie-Tooth disease; small fronto-parietal lesions in Menkes disease; marked signal abnormalities in the myelinised regions in the acute neonatal form of maple syrup urine disease; strip-like involvement of the corpus callosum in glutaric aciduria type 1; persistent periventricular parieto-occipital abnormalities in phenylketonuria; diffuse signal abnormalities with necrotic evolution in global cerebral anoxia or after heroin vapour inhalation; almost completely reversible symmetric fronto-parietal lesions in methotrexate neurotoxicity; chain-like lesions in watershed ischaemia; splenium involvement that normalises in reversible splenial lesions or leads to gliosis in diffuse axonal injury.ConclusionNeuroradiologists must be familiar with these features, thereby preventing misdiagnosis and inappropriate management.
