Aneurysmal subarachnoid hemorrhage is an intracranial hemorrhage caused by a ruptured aneurysm in the subarachnoid space. Although it occurs less frequently than other types of stroke, it is a devastating disease that has an overall mortality approaching 50% and carries a high risk of premature death.1 The diagnostic evaluation of aSAH includes a noncontrast head CT scan, a lumbar puncture, or both. After diagnosis of aSAH, imaging of the cerebral vasculature should be undertaken with cerebral digital subtraction angiography or, in some cases, CTA or magnetic resonance angiography (MRA). If left untreated, there is a significant risk of additional aneurysmal rupture, and patient mortality approaches 50% within 6 months. Treatment of the ruptured aneurysm can be accomplished surgically or by endovascular techniques.2
