What can major bleeding from the brain rubbing against the skull be referred to as?

The term that refers to major bleeding from the brain rubbing against the skull is more accurately described as a hematoma. A hematoma specifically denotes a localized collection of blood outside of blood vessels, which can occur when blood leaks into an area, such as between the brain and the skull.

Hemorrhages generally refer to the act of bleeding itself, which can occur in various forms and locations, but does not specifically describe the encapsulated nature of a hematoma.

Hypoxia and anoxia pertain to deficiencies in oxygen supply to the brain, rather than to blood accumulation or bleeding, and do not describe the phenomenon of bleeding from the brain into the surrounding space. Hence, while hemorrhage may reflect significant bleeding, hematoma is the more precise term that focuses on the resultant pocket of blood that can exert pressure on the brain, leading to neurological complications.
