Fig 2. A and B, Axial T2-weighted MR image of brain (obtained on day 24 postinsult) demonstrates extensive bilateral symmetric white matter hyperintensity extending subcortically, with sparing of the basal ganglia deep gray matter and cortical structures. C, Diffusion-weighted image (DWI) obtained 24 days after initial insult shows leukoencephalopathy, with high signal intensity on isotropic imaging. D, Apparent diffusion coefficient (ADC) mapping confirms restricted diffusion of the cerebral white matter.
