Migrainous aura starting several minutes after the onset of subarachnoid hemorrhage

Abstract
A 39-year old woman acutely developed nausea and severe bilateral headache, rising from the neck to the forehead. Ten minutes later, she experienced visual migrainous aura-like symptoms slowly propagating into one visual hemifield. The scintillation scotoma resolved after ∼25 minutes. The patient had a 15-year history of migraine according to International Headache Society (IHS) criteria. She recalled at least one scintillation scotoma followed but not preceded by headache several months before admission.
