How long does it typically take for a cerebral aneurysm to rupture?

Question

I recently had a cerebral aneurysm rupture and bleed out in my brain. After a very long surgery I am now recovering. I was curious how long it was in my brain before it ruptured?

Answer 1

It is true, there is no way to know.  Although more than likely, it had been there a while. Aneurysms, unless caused by trauma, tend to grow fairly slowly. Some aneurysm locations in the brain can be faster than others due to differences in blood flow.

Answer 2

There is no "typical" in those cases.  There are too many variable.  No way to know.
