Brain [18F]FDG PET-CT imaging in posterior cortical atrophy

A case study of 68-year-old woman with a four-year history of progressive difficulty performing daily activities like dressing, and sometimes colliding with objects when walking is presented. Evaluation revealed apperceptive visual agnosia, simultanagnosia, optic ataxia, oculomotor, dressing and constructive apraxia. Other cognitive domains were relatively spared. Results of the FDG-PET-CT also showed a a neurodegenerative syndrome with an early and progressive decline in visuospatial and visuoperceptual skills, attributable to Alzheimer's disease pathology in most patients.
