Aclient in the intensive care unit who has a brain tumor has experienced a sharp decline. the care team suspects that water and protein have crossed the blood–brain barrier and been transferred from the vascular space into the client’s interstitial space. which diagnosis best captures this pathophysiology?

The correct answer is vasogenic edema.

Explanation:

A kind of cerebral edema in which the blood-brain barrier is disrupted is termed as vasogenic cerebral edema. It refers to extracellular edema that primarily influences the white matter through leakage of fluid from the capillaries.  

It is primarily witnessed surrounding the brain tumors, that is, both primary and secondary and the cerebral abscesses, however, some of the vasogenic edema may be witnessed around the developing cerebral hemorrhage and cerebral contusion.
