Abstract:
We describe a 39-year-old man who developed thunderclap headaches during a hospital admission for accidental superficial burns. His magnetic resonance brain imaging was normal expect for diffuse segmental vasoconstriction. Prior to admission, he was consuming excessive amounts of caffeine which was restarted and slowly tapered and stopped over weeks. Repeat magnetic resonance angiogram showed resolution of segmental vasoconstriction. The implications of prescribed and non-prescribed drugs on cerebral vasculature have been discussed.
