Nontraumatic intracerebral hemorrhage affects more than one million per year worldwide and accounts for 10% of strokes in the United States. Aneurysm rupture is the most common cause of nontraumatic subarachnoid hemorrhage and is often associated with significant morbidity and mortality. Subdural and epidural hemorrhages may be induced by head trauma and can be life-threatening if not closely monitored and treated. The widespread use of systemic anticoagulation agents for cardiac and prothrombotic conditions raises the risk of all types of intracranial hemorrhage and presents unique challenges in acute management. Treatment of intracranial hemorrhage is geared toward minimizing hematoma expansion, reducing increased intracranial pressure, and surgically treating aneurysms, vascular malformations, and herniation syndromes.
