Back to Top Causes. Increased intracranial pressure can be due to a rise in pressure of the cerebrospinal fluid. This is the fluid that surrounds the brain and spinal cord. Increase in intracranial pressure can also be due to a rise in pressure within the brain itself.This can be caused by a mass (such as a tumor), bleeding into the brain or fluid around the brain, or swelling within the brain itself.his is the fluid that surrounds the brain and spinal cord.
