What are Charcot-Bouchard aneurysm?
Charcot-Bouchard aneurysms are minute aneurysms (microaneurysms) in the brain that occur in small penetrating blood vessels with a diameter that is less than 300 micrometers. The most common vessels involved are the lenticulostriate branches (LSA) of the middle cerebral artery (MCA).

Is berry aneurysm a true aneurysm?
A false aneurysm, also known as pseudoaneurysm, involves only the outer layer of the artery (adventitia). Depending on their shape, they can be saccular or fusiform. Cerebral aneurysms are 90% saccular aneurysms (also known as berry aneurysms), unlike aortic aneurysms, which are about 94% fusiform.
Are berry aneurysms fatal?
