Migrainous infarction involving two different arterial territories: report of two cases.

It is reasonable to speculate that migrainous infarction may develop in different territories of cerebral arteries. However, this condition was rarely reported before. Here we described two patients (one woman, 29 year-old; one man, 47 year-old) with a history of migraine with aura, had ischemic strokes during the migraine attack. The ischemic stroke of the female patient involved the territories of the posterior cerebral and anterior choroidal arteries; whereas the male patient had two episodes of ischemic strokes, involving the territories of the middle and posterior cerebral arteries sequentially. Both patients recovered well during the follow-up periods. We suggest that migrainous infarction can involve different arterial territories.
