Presentation
History of old stroke
Patient Data
Large infarct in a left middle cerebral artery distribution,
A contiguous tract of gliosis (high signal at FLAIR WI) leading from the region of cortical and subcortical neuronal injury towards the deep cerebral structures, along the expected topographical course of the involved white matter tract.
MRA revealed occluded left middle cerebral artery.
A contiguous tract of gliosis leading from a region of cortical or subcortical of neuronal injury towards the deep cerebral structures, along the expected topographical course of the involved white matter tract. (Arrows)
Case Discussion
Wallerian degeneration (WaD) is the process of antegrade degeneration of the axons and their accompanying myelin sheaths following proximal axonal or neuronal cell body lesions. It may result following neuronal loss due to cerebral infarction, trauma, necrosis, focal demyelination or hemorrhage.
It is seen as a contiguous tract of gliosis leading from an region of cortical or subcortical of neuronal injury towards the deep cerebral structures, along the expected topographical course of the involved white matter tract.
