	Cerebral aneurysm - Wikipedia, the free encyclopedia
		A cerebral or brain aneurysm is a cerebrovascular disorder in which weakness in the wall of a cerebral artery or vein causes a localized dilation or ballooning of the blood vessel.
		A common location of cerebral aneurysms is on the arteries at the base of the brain, known as the Circle of Willis.
		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.

	The Facts about Cerebral Aneurysm
		A cerebral aneurysm (also known as an intracranial or intracerebral aneurysm) is a weak or thin spot on a blood vessel in the brain that balloons out and fills with blood.
		Cerebral aneurysms can occur anywhere in the brain, but most are located along a loop of arteries that run between the underside of the brain and the base of the skull.
		Cerebral aneurysms are also more common in people with certain genetic diseases, such as connective tissue disorders and polycystic kidney disease, and certain circulatory disorders, such as arteriovenous malformations - congenital malformations in which a snarled tangle of arteries and veins in the brain disrupts blood flow.

		A cerebral aneurysm is an abnormally dilated segment of a blood vessel surrounding the brain.
		Cerebral aneurysms are said to occur in 3-5% of the general population, are more common in patients older than 30, and are almost twice as common in women than men.
		Aneurysms frequently have a thin wall and are particularly prone to rupture (bleeding).

		A cerebral or intracranial aneurysm is a dilation of an artery in the brain that results from a weakening of the inner muscular layer (the intima) of a blood vessel wall (detailed description of cerebral aneurysms).
		An aneurysm is clipped through a craniotomy, which is a surgical procedure in which the brain and the blood vessels are accessed through an opening in the skull.
		Aneurysm clips come in all different shapes and sizes, and the choice of a particular clip is based on the size and location of an aneurysm.

		Aneurysms may also take the form of a bulge in one wall of the artery--a lateral aneurysm--or a widening of the entire artery--a fusiform aneurysm.
		Aneurysms rarely occur in the very young or the very old; about 60% of aneurysms are diagnosed in people between ages 40 and 65.
		Cerebral aneurysms can be caused by brain trauma, infection, hardening of the arteries (atherosclerosis), or abnormal rapid cell growth (neoplastic disease), but most seem to arise from a congenital, or developmental, defect.

		The headache associated with an aneurysm is usually only present when the aneurysm is leaking or it ruptures.
		An asymptomatic aneurysm is often treated by surgery either by placing a clip on it or by inserting a coil into the aneurysm during an angiogram.

		Diagnosis of a ruptured cerebral aneurysm is commonly made by finding signs of subarachnoid hemorrhage on a CT scan (Computerized Tomography, sometimes called a CAT scan).
		If the CT scan is negative but a ruptured aneurysm is still suspected, a lumbar puncture is performed to detect blood in the cerebrospinal fluid (CSF) that surrounds the brain and spinal cord.
		Cerebral angiography, the traditional method, involves introducing a catheter (small plastic tube) into an artery (usually in the leg) and steering it through the blood vessels of the body to the artery involved by the aneurysm.
