Vasogenic cerebral edema
Citation, DOI and article data
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 blood-brain barrier remains 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 a finger-like fashion
- secondary effects of vasogenic edema are similar to cytotoxic edema, with effacement of cerebral sulci, with or without midline shift
