Bilateral Wallerian Degeneration of the Pontocerebellar Tracts
Wallerian degeneration is the process of progressive demyelination and disintegration of the distal axonal segment following the transection of the axon or damage to the neuron. We report a case of a patient with Wallerian degeneration of the pontocerebellar tracts. She had a history of a pontine infarction 3 months ago. Wallerian degeneration of pontocerebellar tracts is seen bilaterally and s...
متن کاملT2/Fluid Attenuation Inversion Recovery Hypointensity of Corticospinal Tracts due to Subacute Stage of Wallerian Degeneration

The T2/FLAIR hypointensity of corticospinal tracts during Wallerian degeneration was initially demonstrated by Kuhn et ...
متن کاملAcute corticospinal tract Wallerian degeneration is associated with stroke outcome.
BACKGROUND AND PURPOSE In children with stroke, poor motor outcome is associated with early Wallerian degeneration of the corticospinal tract that is seen on diffusion-weighted MRI. In this study we test the hypothesis that early diffusion changes also occur in the corticospinal tract (CST) of adults after stroke and that these lesions are associated with poor outcome. METHODS In this retrosp...
متن کاملRetrograde Wallerian degeneration of cranial corticospinal tracts in cervical spinal cord injury patients using diffusion tensor imaging.
Diffusion tensor imaging (DTI) has the potential to reveal disruption of white matter microstructure in chronically injured spinal cords. We quantified fractional anisotropy (FA) and mean diffusivity (MD) to demonstrate retrograde Wallerian degeneration (WD) of cranial corticospinal tract (CST) in cervical spinal cord injury (SCI). Twenty-two patients with complete cervical SCI in the chronic s...
متن کاملDiffusion-weighted imaging of acute corticospinal tract injury preceding Wallerian degeneration in the maturing human brain.
BACKGROUND AND PURPOSE Wallerian degeneration, the secondary degeneration of axons from cortical and subcortical injury, is associated with poor neurologic outcome. Since diffusion-weighted (DW) imaging is sensitive to early changes of cytotoxic edema, DW imaging may depict the acute injury to descending white matter tracts that precedes Wallerian degeneration; this injury is not visible on con...
