[A case of the usefulness of MR angiography and diffusion weighted image to evaluate migraine].

Abstract

A 37-year-old male transported by an ambulance with severe pulsating headache after transient was scintillating scotoma and right hemianopia. He had experienced migraine attacks 2-10 times every year since he was 22 years old. His initial vital signs were stable, the neurological findings while he rested in bed were normal and the head CT examination showed no abnormality. MR angiography revealed narrowing of his cerebral arteries, especially noticeable on the left side. The headache improved after administration of eletriptan hydrobromide. The diffusion weighted image on the next day showed high intensity areas in the left cerebellar hemisphere, vermis, left insular and occipital lobe. The MRA indicated enlargement of the diameter of the cerebral arteries. These findings suggested the usefulness of MRA and diffusion weighted image to evaluate migraine.
