title: 18F-FDG PET/CT findings in a case of a semantic variant of primary progressive aphasia.
abstract: Progressive speech and language disorders are commonly referred to as primary progressive aphasia (PPA), which is a clinical syndrome eroding both speech and language. Functional imaging may reveal the cause of this disorder even if structural imaging is absent. Fluorine-18- fluorodeoxyglucose positron emission tomography/computed tomography ((18)F-FDG PET/CT) allows the assessment of neuronal activity by semi-quantitatively measuring glucose metabolism in the brain. In medical literature, (18)F-FDG PET/CT studies show hypometabolic areas in different regions of the brain which are special clues for differentiating the subgroups of PPA.
  
  
  CONCLUSIONS
  This case was reported to demonstrate the characteristic (18)F-FDG PET CT findings for a semantic variant of PPA.
