what is the difference between a brain aneurysm and a brain hemorrhage?
On brain imaging, aneurysms appear as a bulge and can look like a berry hanging on a stem. This is a blood vessel ballooning with blood because the vein is blocked or obstructed higher up. If this bulge (aneurysm) bursts, blood enters and damages the brain. When this happens, it is referred to as a hemorrhagic stroke.
