An<unk>  is a hemorrhage, or bleeding, within the skull. Intracerebral bleeds are the second most common cause of stroke, accounting for 30–60% of hospital admissions for stroke.
High blood pressure raises the risk of spontaneous intracerebral hemorrhage by two to six times. More common in adults than in children, intraparenchymal bleeds due to trauma are usually due to penetrating head trauma, but can also be due to depressed skull fractures, acceleration-deceleration trauma, rupture of an aneurysm or arteriovenous malformation (AVM), and bleeding within a tumor. A very small proportion is due to cerebral venous sinus thrombosis.
