ABSTRACT
Posterior cortical atrophy(PCA) is a presenile dementia that presents primarily with signs and symptoms of cortical visual dysfunction, while memory is relatively preserved until the late stage of the disease. We report a patient with PCA, confirmed by brain magnetic resonance imaging (MRI) and F18-fluorodeoxyglucose positron emission tomography(FDG PET). A 58-year-old right-handed woman presented initially with visual dimness and difficulty finding things around her. She had partial Balint's syndrome, partial Gerstmann syndrome, and idiomotor apraxia. She also had a mild memory disturbance, but preserved insight of her disease. Neuropsychological evaluation showed decreased parietal and left temporal functions bilaterally. Brain MRI and F18-FDG PET revealed typical bilateral occipitoparietal atrophy and hypometabolism, which were slightly worse on the right side. Cholinesterase inhibitor administration for 6 months improved the memory impairment slightly, but not the cortical visual dysfunction. This is a typical case of PCA, confirmed by neurologic signs and imaging findings.
