1 Answer

Answer :

Cerebral edema is basically a swelling of the brain, which increases pressure within the skull. This can be the result of a closed-head trauma, or an infection of the brain or brain stem. Not to be confused with a hematoma, which also exerts pressure on the brain due to intracranial bleeding.
