© Springer International Publishing Switzerland 2015.Cerebral aneurysms are focal dilations of blood vessel walls that can pouch outwards and compress adjacent structures or rupture and bleed, causing a subarachnoid hemorrhage. Such a hemorrhage can cause symptoms ranging from mild headache to coma, and since an aneurysm that has rupture is at high risk of rupturing again, much emphasis is placed on treating them. Below is an overview of the epidemiology, clinical signs and symptoms, diagnosis and management of cerebral aneurysms.
