  "abstract": "Migrainous infarction is a rare cause of ischaemic stroke. We report such a presentation in a patient with possible competing mechanisms for ischaemic stroke but whose presentation and neuroimaging findings make this the most likely diagnosis. A 61-year-old male with a history of migraine with visual aura developed his typical visual aura in context of his usual trigger of performing a task involving prolonged standing, concentration, bright lights and dehydration. His aura consisted of photopsia that moves from the centre of his vision to the right. The initial episode lasted for 30 minutes before resolution. However, unusually a second episode occurred 30minutes later but persisted until the next day in association with a headache, prompting him to seek medical attention. Examination confirmed a small visual field defect just right of centre vision. An MRI Brain demonstrated a small wedge-shaped area of diffusion weighted restriction in the left occipital lobe, consistent with an ischaemic infarct, localising anatomically to the origin of the visual aura, subsequent imaging demonstrated evolution into a small T2/FLAIR hyperintensity. We review the literature on migranous infarction to discuss clinical presentation and diagnostic criteria, pathophysiology from vessel constriction to endothelial dysfunction and management.iberedemewang@gmail.com",
