Cerebral oedema 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 oedema and cytotoxic cerebral oedema, the latter a commonly used term used to denote both true cytotoxic oedema and ionic oedema 4. Additionally, although traditionally not included in discussions on oedema, haemorrhagic transformation can be thought of an extreme end-stage form of the same processes which lead to oedema.
As such a more precise classification is 3-4:
- cytotoxic cerebral oedema
- ionic cerebral oedema
- vasogenic cerebral oedema
- haemorrhagic transformation
Special types of oedema to be considered:
- transependymal oedema (also known as interstitial cerebral oedema)
- combined cerebral oedema
