Subarachnoid Hemorrhage
In a subarachnoid hemorrhage, blood accumulates in the space beneath the inner arachnoid layer of the meninges. The injury is often associated with an intracerebral bleed (see below).

Subarachnoid hemorrhage - Bleeding from a blood vessel on the surface of the brain into the space between the brain and the skull.

In a subarachnoid hemorrhage, a blood vessel on the surface of the brain leaks blood or ruptures. When this happens, bleeding occurs between the inner and middle layers of the membranes that cover the brain.

Definition A subarachnoid hemorrhage is an abnormal and very dangerous condition in which blood collects beneath the arachnoid mater, a membrane that covers the brain. This area, called the subarachnoid space, normally contains cerebrospinal fluid.
