case_images: Axial T2 (a), Axial T1 plain (b), and post-contrast (c). In addition, axial susceptibility weighted imaging (SWI) (d), diffusion (e), and coronal fluid-attenuated inversion recovery (f) show diffuse and confluent white matter hyperintensity (marked by arrow) surrounding the giant perivascular spaces (arrow head). There is associated gyral expansion over the perivascular spaces with no enhancement. The SWI shows no hemorrhage or calcifications. There is no diffusion restriction (e) or post-contrast enhancement (c).
