Cerebral œdema (or cerebral edema) is a build-up of extra fluid in the brain. It causes swelling. It is caused by physical trauma or an injury to the brain. This includes inflammation of the brain caused by some infections.[1] Also, mountain climbers at high altitude have been known to experience cerebral oedema primarily due to reduced air pressure acting on the cranium.
