Transient vasoconstriction and dilatation of cerebral arteries, a newly identified syndrome, may cause severe headaches and neurological deficits. Further research is needed to define its causes and differentiate it from other cerebrovascular diseases.

Area of Science:

  • Neurology
  • Vascular Neurology
  • Neuroimaging

Background:

  • Cerebrovascular disease is typically not attributed to vasoconstriction, with exceptions like subarachnoid hemorrhage vasospasm and migraine.
  • The Circle of Willis arteries are crucial for brain blood supply.

Observation:

  • Four patients presented with severe headaches and fluctuating neurological deficits.
  • Angiography revealed transient, reversible vasoconstriction and dilatation in arteries around the Circle of Willis.
  • No underlying cause was identified for these clinical and angiographic findings.

Findings:

  • A novel clinical-angiographic syndrome characterized by reversible cerebral artery vasoconstriction and dilatation has been identified.
  • This syndrome presents with severe headaches and transient neurological deficits.

  • The condition affects arteries around the Circle of Willis.

    • Implications:

    • This newly recognized syndrome requires differentiation from other cerebrovascular conditions.
    • Identifying precipitants of reversible vasoconstriction is crucial for better patient management.
    • Further studies are needed to understand the etiology and long-term outcomes of this condition.
