Summary

A patient developed parkinsonism after a hypoxic-ischemic insult. Brain pathology revealed old infarcts and microhemorrhages, correlating with MRI findings and clinical symptoms.

Area of Science:

  • Neurology
  • Neuroimaging
  • Pathology

Background:

  • Parkinsonism can manifest after hypoxic-ischemic brain injury.
  • Basal ganglia lesions on MRI may indicate underlying pathology.

Observation:

  • A 72-year-old patient presented with parkinsonism post-hypoxic-ischemic insult.
  • T1-weighted MRI showed high signal intensity lesions in the basal ganglia.

Findings:

  • Pathologic examination revealed multiple old infarcts with gliosis.
  • Evidence of prior microhemorrhage (lipid-laden and hemosiderin-laden macrophages) was found.

Implications:

  • Pathologic findings correlate with clinical parkinsonism and MRI abnormalities.
  • This case highlights the link between hypoxic injury, vascular changes, and movement disorders.
