Abnormally high pressure within the skull is known ​as Increased intracranial pressure

Increased intracranial pressure is an abnormal rise in the pressure inside the skull that can result from or cause brain injury. It can be due to a rise in pressure of the cerebrospinal fluid (CSF). CSF is the fluid that surrounds the brain and the spinal cord. It can also be due to a rise in pressure within the brain itself. Presence of a mass (such as a tumor), bleeding into the brain or fluid around the brain, and swelling within the brain can also cause increased intracranial pressure.
