Scope Note
congenital or acquired abnormal outpouching of an intracranial blood vessel wall; saccular (berry) aneurysms are the most common variant, and tend to form at arterial branch points near the base of the brain; rupture results in subarachnoid hemorrhage or intracranial hemorrhages; giant aneurysms (>2.5 cm in diameter) may compress adjacent structures, including the oculomotor nerve.

Facts (generated by robot; please edit if you find it inaccurate)
- A cerebral aneurysm is usually diagnosed by tests to determine the cause of bleeding within the brain: A CT scan of the head can identify bleeding and occasionally locate the aneurysm.
- Rupture of a cerebral aneurysm is dangerous and usually results in bleeding into the meninges or the brain itself, leading to a subarachnoid hemorrhage or intracranial hematoma, either of which constitutes a stroke.
- Other treatment for cerebral aneurysm is symptomatic and may include anticonvulsants to prevent seizures and analgesics to treat headache.
