Intracranial dural arteriovenous fistulae (DAVF) are acquired fistulous communications between dural arterial branches and dural venous sinuses or cortical veins with the nidus located within the leaflets of the duramater. Dementia and Parkinsonism are amongst the rarest of clinical presentations in DAVFs and are important to diagnose early, being treatable with timely intervention. We present an interesting case of a patient who presented with rapidly progressive dementia and features of parkinsonism who was diagnosed to have extensive DAVF and made remarkable recovery after embolization of the fistulae.
