Figure 1. Magnetic resonance imaging shows symmetrical periventricular white matter hyperintensity (arrows) in axial T2-weighted (b), fluid-attenuated inversion recovery (c), and diffusion-weighted imaging (d) images, along with corresponding changes in T1-weighted images (a). The characteristic "sunflower-like" change is readily apparent, particularly in the T2-weighted image. Increased signal is also visible in the cerebellar dentate nuclei (arrowheads). Gray matter-white matter differentiation is preserved
