title: Rupture of middle fossa arachnoid cyst simulating new-onset migraine with aura.
abstract: Arachnoid cysts represent a common, innocent, finding in routine neuroimaging of headache patients. We present the first report of symptomatic migraine with aura caused by the spontaneous rupture of a middle fossa arachnoid cyst into the subdural space. Brain imaging enabled an accurate diagnosis and, subsequently, adequate surgical management.
