Abstract

Insights

Migraine without aura (MO) can be associated with reversible ischemic-like brain lesions. Advanced MRI techniques may reveal subtle, transient cortical changes in MO patients, suggesting migrainous infarction is possible.

Area of Science:

  • Neurology
  • Neuroimaging

Background:

  • The relationship between migraine and stroke is complex and debated.
  • Reversible brain lesions have been noted in migraine patients, particularly those with aura or complicated attacks.

Observation:

  • A patient experienced a migraine without aura (MO) followed by temporary left-hand weakness.
  • Initial MRI showed a cytotoxic-like lesion, which resolved by day 8.
  • High-resolution MRI revealed a small cortical lesion, and functional MRI showed normal cortical activation after 8 months.

Findings:

  • The patient's MO attack was linked to a transient ischemic-like lesion.
  • The lesion completely reversed on follow-up MRI, supporting the concept of migrainous infarction in MO.

Implications:

  • Migrainous infarction may occur in migraine without aura (MO).
  • Subtle cortical lesions associated with migraine might be more common than previously thought.
  • Advanced neuroimaging techniques are crucial for detecting transient migrainous lesions.
