Cerebral aneurysm is an intracranial weakening of an arterial blood vessel in the brain giving rise to a blister filled with serous fluid(blood). Due to this weakening area, if par-adventure the blister bursts, it can result to subarachnoid hemorrhage. Subarachnoid hemorrhage is mostly accustomed to bleeding into the space surrounding the brain which is caused by ruptured Cerebral aneurysm.
