Area of Science:

  • Neurology
  • Radiology

Background:

  • Subarachnoid hemorrhage is a critical diagnosis for thunderclap headache.
  • Hypertensive encephalopathy can mimic other neurological emergencies.

Observation:

  • A 68-year-old woman presented with thunderclap headache.
  • Initial workup including CT head and CSF analysis was negative for subarachnoid hemorrhage.

Findings:

  • MRI revealed white matter abnormalities in the parieto-occipital regions.
  • No aneurysm was detected on magnetic resonance angiography.
  • Posterior leukoencephalopathy syndrome was diagnosed.

Implications:

  • Hypertensive encephalopathy with reversible posterior leukoencephalopathy can manifest as thunderclap headache.
