[Elevation of cerebral lactate detected by localized 1H magnetic resonance spectroscopy in a patient with migraine].
Localized 1H magnetic resonance spectroscopy was performed in a 45-year-old woman with migraine. She developed throbbing headache attacks without aura since thirteen years ago and the attack was accompanied with right hemiplegia since seven years ago. Brain MRI showed no abnormalities and 123I-IMP SPECT revealed mild frontal dominant decrease of cerebral blood flow. It seemed that her condition was positioned between migraine with prolonged aura and migrainous infarction of complicated migraine in the classification of International Headache Society. Spectra obtained from bilateral frontal lobe interictally showed elevation of lactate at left side. Choline, creatine, and N-acetyl-aspartate were almost equal on both side. The above results suggest that slight ischemia which is not detected by MRI is present or there is a disturbance of oxidative glycolysis, which is induced by mitochondrial dysfunction.
