Abstract
We report the case of a 64-year-old man with migrainous infarction, giving special attention to chronological changes in neuroimaging findings. Five days after the onset, diffusion-weighted imaging showed slightly high intensity, and the apparent diffusion coefficient map showed increased diffusion in the right occipital lobe, which indicated vasogenic edema. Perfusion magnetic resonance imaging (MRI) and MR angiography demonstrated hyperperfusion of the ipsilateral hemisphere. Follow-up MRI showed irreversible brain damage. These images may reflect chronological changes in cerebral edema due to prolonged hyperperfusion with migraine.
