Abstract

The differential diagnosis between Alzheimer's Disease and Frontotemporal Dementia is based on clinical evaluation, however 2-[¹⁸F]-FDG-PET allows the recognition of different metabolism patterns that are useful for distinguishing these entities.

We present the case of a patient with the clinical suspicion of Frontotemporal Dementia who underwent 2-[¹⁸F]-FDG-PET, which showed a metabolism pattern characteristic of Alzheimer's Disease.
