Dolichoectasia of vertebrobasilar arteries leading to vascular dementia: A case report

Abstract

The term dolichoectasia stands for a dilated, elongated and tortuous vessel. Dolichoectasia of the cerebral vasculature is rare but well-described and commonly involves vertebral and basilar arteries. It may be an incidental finding or the patient may present with local compression leading to hydrocephalus, cranial nerve palsies or with ischemic symptoms. We present a case of dolichoectasia of basilar artery contributing to multiple cerebral thromboembolisms where the patient presented with cerebellar symptoms and signs with vascular dementia.
