Most studies of clinically relevant cerebral edema emphasize the effect of added tissue fluid in white matter on gross distortion with transtentorial and subfalcine brain herniation. Our recent studies on altered tissue fluid compartmentation in cerebral gray matter suggest that significant microdistortion of relationships of capillaries to subserved tissue(More)
