case_images: PET showed diffused hypometabolism of the cortical and subcortical regions of the two cerebral lobes, sparing partially the occipital cortex, the basal ganglia and the cerebellar cortex (Figure 1). Patient evolution was marked by a fluctuating hyperactive delirium treated by quetiapine, clonidine and melatonin.

  18F-FDG PET. Diffuse cortical hypometabolism predominant in the right hemisphere, with a preservation of the primary sensorimotor areas. Normal metabolism of the sub-cortical structures and the cerebellum.

case_images: A brain 18F- FDG PET showed a moderate hypometabolism in the frontal, temporal and parietal regions, sparing the motor, and pre-motor cortex (Figure 2).
