3D Stereotactic Surface Projection of FDG PET of our patient showed hypometabolism in bilateral occipital lobes, posterior parietal lobes, and to a lesser extent, bilateral frontal lobes. The metabolism in posterior cingulate gyri and bilateral temporal lobes is preserved. These findings were supportive of Dementia with Lewy Body (DLB). Involvement of the frontal lobes goes against this being a Posterior Cortical Atrophy variant of Alzheimer’s dementia
