MR images of the patient. (A) MRA image of first onset period, 12 days after onset. MRA showed dilation of the left middle cerebral artery (long-tail arrow), with apparent dilation of superficial temporal arteries (long dotted arrow). (B) MRA image of remission period, 27 days after onset. MRA showed that the superficial temporal arteries were retracted. (C) MRA images of recurrence period, 68 days after onset. MRA showed that the left middle cerebral artery appeared normal, and the right middle cerebral artery was dilated. (D) ASL image of first onset period, 12 days after onset. ASL showed hyperperfusion in the left occipital-temporal-parietal focal areas. (E) ASL images of recurrence period, 68 days after onset. ASL showed hyperperfusion in the right occipital-temporal-parietal focal regions. (F) MRS image of first onset period, 12 days after onset. MRS showed a double inverted lactate peak at 1.33 ppm (short dotted arrow). (G) Genotypic detection analysis showed mitochondrial mutation (m.3243A >G).
