Neuroimaging of patient 2. A: Computed tomography of the head showed no hyperdensity; B: Computed tomography perfusion showed no abnormalities, with normal perfusion of the basal ganglia; C: Susceptibility weighted imaging showed low signal intensity in the left basal ganglia; D and E: Diffusion-weighted imaging showed an acute patchy ischemic stroke in the left temporal lobe and that the basal ganglia was spared; F-H: Diffusion tensor imaging confirmed fewer white matter fiber tracts on the left side than on the opposite side.
