Within a few weeks of thiamine depletion, there is a reduction in the activity of the enzymes involved, the end-result being loss of the osmotic gradients in astrocytes and neuronal tissue, with vasogenic
and cytotoxic oedema and subsequent cell necrosis.
The genesis of peritumoral vasogenic
brain edema and tumor cysts: a hypothetical role for tumor-derived vascular permeability factor.
6 cm ring-enhancing lesion within the posterior aspect of the right frontal lobe that had mild surrounding vasogenic
edema and local mass effect-findings that are typical for a pyogenic abscess (Figure 1a).
Simultaneously, AQP4 facilitated the clearance of vasogenic
cerebral edema in pathologies where edema fluid accumulates in the extracellular space (Papadopoulos et al.
They tend to have no surrounding mass effect or vasogenic
edema, unless complicated by superimposed hemorrhage.
The baby was diagnosed with life-threatening bacterial poisoning resulting from hypoxemia caused by vasogenic
shock, poisoning, and low vascular perfusion that led to bluish limbs due to the lack of adequate oxygen.
However, the BBB becomes permeable to mannitol and it may worsen vasogenic
CT and MRI demonstrate surrounding vasogenic
oedema, mass effect and ring enhancement of the abscess.
A follow-up computed tomography of the brain demonstrated the area of infarct with worsened surrounding vasogenic
edema and midline shift of structures (see Figure 1).
In this condition, plasma and red blood cells are transferred into the extracellular space and vasogenic
Vasospasm could occur as a result of exposure of spinal cord to red blood cells and inflammatory mediators and vasogenic
edema could result from the breakdown of blood-spinal cord barrier.
The incidence of vasogenic
edema (ARIA-E) was approximately 1 percent, occurring in 11 patients treated with solanezumab and 5 patients on placebo, which was not statistically significant.
