    Abstract:
    A 40-year-old female suffering from recurrent migrainous strokes is reported. She did not show any muscle weakness or wasting. Ragged red and cytochrome c oxidase negative fibers were present in the muscle biopsy. Muscle mitochondrial DNA analysis showed a 5 kb deletion, without a point mutation at nucleotide pair 3243 in the mitochondrial tRNALeu(UUR) gene. Phosphorus nuclear magnetic resonance spectroscopy of brain and gastrocnemius muscle showed a defective energy metabolism in both organs. An increased inorganic phosphate to phosphocreatine ratio due to a decreased phosphocreatine content was found in the occipital lobes, while an abnormal work-energy cost transfer function and a low rate of phosphocreatine post-exercise recovery were found in the muscle.
