Cytotoxic edema
• Is cell swelling caused by damaged molecular sodium–potassium ATPase ion pumps. It can affect both gray and white matter.
• Is caused by cell death, most commonly due to infarct or excitotoxic (secondary to excessive neurotransmitter stimulation) brain injury.

Vasogenic edema
• Is interstitial edema caused by increased capillary permeability, by breakdown of the tight endothelial junctions comprising the BBB, secondary to either physical disruption or release of vasoactive compounds
• It is seen primarily in the white matter

Interstitial edema
• Is caused by imbalances in CSF flow, most commonly due to obstructive hydrocephalus.
• Presents on imaging as periventricular fluid, often called “transependymal flow of CSF,” most commonly the periventricular white matter.
