Dolichoectasia of Anterior and Posterior Circulation With Thrombosed Saccular Aneurysm of Vertebral Artery Presenting as Obstructive Hydrocephalus: A Case Report

Vertebrobasilar dolichoectasia (VBD) is characterized by vascular elongation, widening, and tortuosity of cerebral vasculature. There are only a few reported cases of VBD as a cause of hydrocephalus. Here, we report a case in a 55-year-old male who presented with sudden vomiting for a day and worsening of headache for two weeks. He was diagnosed with CT imaging with angiographic findings: thrombosed saccular aneurysm of the vertebral artery along with dolichoectasia of the anterior and posterior circulation.
