Fig 3. Involvement of the frontal and parietal lobes in patients with isolated cortical hyperintensities. A, Sagittal FLAIR-weighted scan of a 58-year-old patient 3.5 months after the disease onset and 1 week before death showing signal-intensity increases of the frontal and parietal lobes. B, Axial FLAIR-weighted scan of the same patient showing frontal and parietal signal-intensity increases. C, Diffusion-weighted scan of the same patient showing frontal and parietal signal-intensity increases.
