Cerebral edema refers to a number of interconnected processes which result in abnormal shifts of water in various compartments of the brain parenchyma.
It has traditionally been broadly divided into vasogenic cerebral edema and cytotoxic cerebral edema, the latter a term commonly used to denote both true cytotoxic edema and ionic edema 4. In addition, although traditionally not included in discussions on edema, hemorrhagic transformation can be thought of as an extreme end-stage form of the same processes which lead to edema.
As such a more precise classification is 3-4:
