There is moderate to severe hypometabolism affecting large regions of bilateral frontal lobes, worse on the left, especially along its mesial aspects and along the left lateral sulcus. There is also moderate left parietotemporal hypometabolism. No significant hypometabolism of the posterior cingulate gyrus, precuneus, occipital lobes, basal ganglia or thalamus.
In summary, moderate to severe bilateral frontal lobe hypometabolism is compatible with frontotemporal dementia. Features are not those of Lewy body dementia or Alzheimer disease.
