Migrainous stroke causing bilateral anterior cerebral artery territory infarction.

A 38-year-old man developed bilateral anterior cerebral artery territory infarction during the course of a migraine. Magnetic resonance imaging showed bilateral ischemic lesions involving the cortex of the paramedian region of the frontal and parietal lobes, more prominent on the right. Cerebral angiography was normal. To our knowledge, this is the first report of bilateral anterior cerebral artery territory infarction from migraine.
