Abstract
- Semantic variant primary progressive aphasia (svPPA), a well-known subtype of the frontotemporal dementia often shows peculiar clinical features and structural neuroimage findings. To strengthen the accuracy of a clinical diagnosis, amyloid positron emission tomography-computed tomography (PET-CT) might be helpful. However, in patients with late-onset svPPA, an admixture of the various neuropathology would interfere with diagnostic approach. Herein, we report a case of late-onset bilateral svPPA showing a regional amyloid deposition on PET-CT scan.
