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. Cytotoxic cerebral edema refers to a type of cerebral edema, most commonly seen in cerebral ischemia, in which extracellular water passes into cells, resulting .

Two thirds of the meningiomas in our series had peritumoral edema.
Traumatic brain injury may be classified as diffuse or focal. Once plasma constituents cross the barrier, the edema spreads; this may be quite rapid and extensive.
The patient with DKA exema a very deep volume depletion. As the pathophysiology of these two types of edema is different, as is their imaging, they are discussed separately. Brain edema in head injury.
Case 3 – lung cancer metastasis, cystic Case 3 – lung cancer metastasis, cystic. Plasma can be diluted by several mechanisms, including excessive water intake or hyponatremiasyndrome of inappropriate antidiuretic hormone secretion SIADHhemodialysisor rapid reduction of blood glucose in hyper osmolar hyperglycemic state HHSformerly known as hyperosmolar non-ketotic acidosis HONK.

Interstitial edema occurs in obstructive hydrocephalus due to a rupture of the CSF—brain barrier. From Wikipedia, the free encyclopedia. There is growing evidence in the literature that vascular endothelial growth factor VEGF is a key factor in the pathogenesis of peritumoral edema.
We studied by immunohistochemical techniques the expression of VEGF and its receptor flk -1 in meningiomas. This causes a rapid uptake of water and subsequent swelling of the cells.
