The constellation of symptoms and findings in this patient prompted workup for unusual causes of both stroke and neurodegenerative disorder.CASE PRESENTATION: A woman in her sixties presented with visual disturbances, followed by weakness in her right arm and aphasia three days later. Her close acquaintances had suspected progressive cognitive decline during the previous year. CT and MRI showed an occluded left posterior cerebral artery with a subacute occipito-temporal infarction. The finding of extensive white matter lesions and segmental arterial vasoconstriction necessitated further workup of vasculitis and hereditary small vessel disease, which were ruled out. The stroke aetiology was considered to be atherosclerotic intracranial large vessel disease. FDG-PET scan revealed decreased metabolism in the left hemisphere, and cerebrospinal biomarkers had slightly decreased beta-amyloid. The findings were suggestive of early Alzheimer's disease or primary progressive aphasia, but currently inconclusive.INTERPRETATION: Based on clinical-anatomical correlation, the patient's visual disturbances, in this case right hemianopsia and object agnosia, were solely related to the stroke and not to a neurodegenerative disorder. Knowledge and interpretation of visual agnosias can in many cases be clinica...
