BACKGROUND
Sub-arachnoid hemorrhage, cerebral venous thrombosis and cerebral reversible angiopathies are the main causes of secondary thunderclap headache. Ischemic stroke is rarely revealed by thunderclap headache.
METHODS
A 80-year-old woman developed for the first time a thunderclap headache associated with transient distal motor deficit of the right hand. Diffusion-weighted sequences revealed a recent left infarct in a vascular border zone.
CONCLUSIONS
Ischemic stroke is a rare cause of thunderclap headache but practitioners should bear in mind this etiology when the diagnostic work-up is negative. Diffusion-weighted sequences of the brain MRI can provide the diagnosis.
