title: Intracranial dural arteriovenous fistula presenting as parkinsonism and cognitive dysfunction.
abstract: There are few syndromes of parkinsonism with dementia which can be treated. We report two patients with dural arteriovenous fistula (DAVF) who presented with rapidly progressive parkinsonism and cognitive dysfunction. DAVF are rare lesions resulting from abnormal connections between meningeal arteries and dural sinuses. Angiography in both patients revealed DAVF associated with multiple occlusive changes in the dural venous sinus. This report emphasizes the need for a high level of clinical suspicion to diagnose DAVF and consider it as one of the causes of rapidly progressive cognitive dysfunction in patients with parkinsonism.
