Case ReportsA novel approach to diagnose reversible cerebral vasoconstriction syndrome: a case series.
Reversible cerebral vasoconstriction syndrome (RCVS) is classically diagnosed based on the presence of severe thunderclap headache, focal neurologic symptoms, and the radiographic findings of reversible diffuse segmental cerebral vasoconstriction. We present a diagnostic test that may assist in the clinical diagnosis and facilitate treatment. ⋯ Our small case series suggest that IA administration of vasodilators is safe and may aid in distinguishing vasodilator responsive syndromes such as RCVS from other causes. Further study is required with long-term clinical outcome to determine the utility of this diagnostic test.
