The patient’s cranial imaging findings. a-j Magnetic resonance imaging showed abnormal signals in the bilateral frontoparietal subcortical area, periventricular region of the lateral ventricle, basal ganglia, and dorsal thalamus. The bilateral external capsules (c) and left temporal pole d and i were affected as indicated by arrows. h, SWI revealed multiple hemosiderin depositions or minor hemorrhage lesions in the bilateral basal ganglia, dorsal thalamus, and right parietal lobe. j, MRA indicated reduced distal branches of the cerebral arteries. k-o, 18Fluoro-deoxy-glucose-PET/CT showed reduced glucose metabolism in the bilateral lobes, basal ganglia, and thalamus
