In one case, the headache was associated with atypical subarachnoid haemorrhage. The variable nature of the headache and the degree of associated hypertension raised the clinical suspicion of reversible cerebral vasoconstriction syndrome, confirmed on MR angiography. Both patients took nimodipine until the cerebral vasoconstriction had resolved radiologically.
