Vasogenic cerebral edema refers to a type of cerebral edema in which the blood brain barrier (BBB) is disrupted (cf. cytotoxic cerebral edema, where the BBB is intact). It is an extracellular edema which mainly affects the white matter via leakage of fluid from capillaries.
- grey-white matter differentiation is maintained and the edema involves mainly white matter, extending in finger-like fashion
- secondary effects of vasogenic edema are similar to cytotoxic edema, with effacement of cerebral sulci, with or without midline shift
