Steroids are not beneficial in the treatment of cytotoxic edema secondary to stroke, and may, in fact, be harmful in cytotoxic edema from trauma 7. Edea cells swell due to inward shift of water, the there is a commensurate decrease in diffusion, identified as high signal on DWI and low signal on ADC. As the pathophysiology of these two types of edema is different, as is their imaging, they are discussed separately.

Fast travel to high altitude without proper acclimatization can cause high-altitude cerebral edema HACE. This creates an abnormal pressure gradient and movement of water into the brain, which can cause progressive cerebral edema, resulting in a spectrum of signs and symptoms from headache and ataxia to seizures and coma.
