Figure 1: (a–c) - T1- and T2-weighted magnetic resonance imaging (MRI) of the brain in axial sections demonstrates hyperintense signals in the right putamen, caudate, and globus pallidus in the fourth patient (blue arrows). (d and e) - Small areas of hypointense signal are observed on T2-weighted and fluid-attenuated inversion recovery images (green arrows). (f) Diffusion restriction not appreciated on diffusion-weighted imaging
