However, CT scan can be limited in determining the exact cause of cerebral edema in which cases, CT angiography (CTA), MRI, or digital subtraction angiography (DSA) may be necessary. MRI is particularly useful as it can differentiate between cytotoxic and vasogenic edema, guiding future treatment decisions. [1]
Cerebral edema is mainly classified into cytotoxic edema, vasogenic edema and interstitial edema. Cytotoxic edema affects both the white and gray matter and results from the swelling of cellular elements such as neurons, glia and endothelial cells. Vasogenic edema affects white matter and results from blood brain barrier (BBB) breakdown ...
While there is strong evidence that vasogenic edema plays a major role in HACE, cytotoxic edema, cellular retention of fluids, may contribute as well. [13] [18] Cytotoxic edema may be caused by the failure of cellular ion pumps, which results from hypoxia. Then intracellular sodium and osmolarity increase, and there is an influx of water that ...
ARIA-E refers to cerebral edema, involving the breakdown of the tight endothelial junctions of the blood-brain barrier and subsequent accumulation of fluid. [3] In a double-blind trial of the humanised monoclonal antibody solanezumab (n = 2042), sixteen patients (11 taking the drug, 5 taking a placebo), or 0.78% developed ARIA-E.

Thanks to their No. 1 seed, the Chiefs have a bye for the wild-card round of the playoffs. From there, they'll take on the lowest seed remaining in the AFC.
The "cytotoxic" theory suggests that it is direct cell damage by toxins (usually medications) that precipitates the edema. The "immunogenic" theory suggests a role for the immune system (specifically T cells). [1] [5] Some consider the cytotoxic and immunogenic theories together as a single "toxic" theory. [4]
