Overview

Spontaneous SAH is most often due to rupture of cerebral aneurysms (85%), which are weaknesses in the wall of the arteries of the brain that enlarge. While most cases of SAH are due to bleeding from small aneurysms, there is evidence from research that larger aneurysms (which are rarer) are still more likely to rupture. A further 10% of cases is due to non-aneurysmal perimesencephalic hemorrhage, in which the blood is limited to the area of the midbrain. No aneurysms are generally found. The remaining 5% are due to vasculitic damage to arteries, other disorders affecting the vessels, disorders of the spinal cord blood vessels, and bleeding into various tumors.
