"Once cytotoxic oedema has occurred (sodium, chloride and water have moved intracellularly) and provided there is some replenishment of blood in the capillaries, a sodium (Na+) concentration gradient exists from the capillary lumen, across the endothelium and into the extracellular space. Sodium is transported into the extracellular space, drawing with it chloride (along a electrochemical gradient) and water (along an osmotic gradient) 1."

"grey-white matter junction becomes blurred i.e. there is a loss of grey-white differentiation; this is distinct from vasogenic oedema where the grey-white matter distinction becomes more pronounced"
"unlike vasogenic oedema, it will usually be accompanied by restricted diffusion on diffusion weighted imaging sequences; this is due to the presence of underlying cytotoxic oedema which precedes ionic oedema in the acute and subacute phase"
