What's a brain aneurysm?

Berry aneurysm

Heart
The most common and classic brain aneurysm is the berry or saccular aneurysm. These appear as a ballooning at the branchpoints of cerebral vessels typically at the base of the brain in the Circle of Willis. These are usually asymptomatic until there is a devastating hemorrhage from them. The treatment is to obliterate the aneurysm with surgery or endovascular (coiling techniques).

why do i have aneurysms?

Aortic?

Open-uri20120821-22215-1967oog
For Aortic Aneursyms: We are not quite sure what actually causes an AAA to form in some people. The leading thought is that the aneurysm may be caused by inflammation in the aorta, which may cause its wall to weaken or break down. Most believe that this inflammation can be associated with atherosclerosis (also called hardening of the arteries) or risk factors for atherosclerosis - high BP, smoking

Benign bone tumor

Bone
An aneurysmal bone cyst is a benign condition of the bones, commonly in a child which can lead to fractures. The cyst area often expands and weakens the bone, making it prone to fracture. The fracture typically heals, but the condition may persist and fracture may occur again, sometimes necessitating surgery. The humerus bone near the shoulder is a common location for this.

What is an aortic aneurysm?

Weak wall

Aneurysm
The aorta is a living pipe. It has 3 layers, the inner layer or intima, the middle layer or media were some muscle like cells dwell and the adventitia rich in collagen fibers. The process of arteriosclerosis may result in slow death of the media which then gets replaced by collagen scar. The pressure inside the aorta and the wall weakness will result in dilatation of the aorta and it could burst.
