What is an intracranial aneurysm?

Mondo Health Updated on 2024-02-24

Brain aneurysms, also known as intracranial aneurysms, are balloon-like bulges in blood vessels in the brain, and aneurysms often look like berries hanging from stems.

At present, it is believed that the formation and growth of cerebral aneurysms are caused by the shear force of blood flowing through blood vessels on the weak areas of the blood vessel wall, which can lead to the enlargement or even rupture of cerebral aneurysms. Once a brain aneurysm ruptures, it can lead to bleeding in the brain, known as hemorrhagic stroke.

Most often, a ruptured brain aneurysm occurs in the space between the brain and the membrane tissue that covers the brain. This type of hemorrhagic stroke is called subarachnoid hemorrhage.

Brain aneurysms are common, with one in 50 people having an unruptured brain aneurysm, and many people don't even know they have a brain aneurysm.

Most small aneurysms have a low risk of rupture, are not serious, and they usually don't cause noticeable symptoms. In many cases, asymptomatic brain aneurysms are found during the examination of other disorders.

However, once an aneurysm ruptures, it is life-threatening and needs to be done immediately**.
