Abstract
Patients with arterial aneurysms in the basilar tip location represent a therapeutic challenge. Various studies have shown the cause of Basilar Tip Aneurysm (BTA) as a multifactorial process which involves factors like genetic, anatomic, and environmental risk factors. The present review aims to discuss the risk factors, epidemiology, familial aneurysm, prevalence of basilar tip aneurysm and author's opinion on the importance of the role of radiology in the diagnosis and treatment of BTA.
