Figure 1: Magnetic resonance imaging of the brain T1 axial images (a and b) showing a concentric ring pattern of the lesion (hypointense center with isointense periphery) within the bilateral parietal subcortical region. Axial fluid-attenuated inversion recovery images (c and d) showing corresponding lesions with alternating hypointense and hyperintense concentric rings
