Abstract
|
|
|
|
Bilateral internal carotid artery (ICA) occlusion is a rare cerebrovascular disease. Chronic ICA occlusion is not always associated with neurological deficits, but it can lead to visual disturbance, TIA, non-fatal stroke, and catastrophic stroke presenting with coma. A 60-year-old man with bilateral ICA occlusion who presented with psychosis and dementia followed by sudden loss of consciousness is described. His clinical history and MRI findings suggested vascular dementia, but his psychotic features were difficult to explain without bilateral ICA occlusion. F18-FDG PET findings mimicked typical Alzheimer’s disease and caused diagnostic confusion. To our knowledge, this is the first reported case of bilateral ICA occlusion associated with psychosis and dementia.
