Area of Science:

  • Neuropathology
  • Neuroimaging
  • White Matter Disorders

Background:

  • Presenile dementia and hemiplegia indicate severe neurological compromise.
  • Sporadic cases of leukoencephalopathy are rare and challenging to diagnose.
  • Understanding white matter diseases is crucial for neurodegenerative disorder research.

Observation:

  • A 51-year-old woman presented with progressive presenile dementia and spastic hemiplegia.
  • Brain MRI revealed widespread abnormalities in the cerebral deep white matter and corpus callosum.
  • Neuropathology showed extensive axonal and myelin destruction with axonal spheroids, particularly in frontoparietal white matter.

Findings:

  • The case represents the third documented sporadic instance of neuroaxonal leukoencephalopathy with axonal spheroids.

  • Pathological heterogeneity suggested sequential white matter degenerative processes.
  • Cerebral cortex and subcortical U fibers were notably spared.

    • Implications:

    • This case expands the understanding of rare leukoencephalopathies.
    • Further research into sporadic neuroaxonal leukoencephalopathy is warranted.
    • Identifying distinct pathological features aids in differential diagnosis of white matter diseases.
