Researchers claim that cytotoxic edema is the main mechanism related to cell-cytokine interaction in neurons and microglial cells (4).
The typical MRI lesions are symmetrical white matter vasogenic edema, usually located parieto-occipital region sparing calcarine and paramedian regions, which may show progression to cytotoxic edema, infarctions, hemorrhages, laminar necroses and glioses (2).
A repeated brain MRI showed bilateral cortical and subcortical hyperintensity involving the parieto-occipital areas on FLAIR and diffusion-weighted images, with a decreased apparent diffusion coefficient [Figure 1]d,[Figure 1]e,[Figure 1]f, whereas the second neuroimaging findings were in accordance with cytotoxic edema. We, therefore, conducted a cerebral angiography in order to identify the cause of infarction.
However, treatment should be based on accurate diagnosis.8 Once lacunar infarction attacks, lesions with large volume are usually rare; metabolism of brain cells will be affected by ischemia and anoxia of cerebral tissues, which will restrain the functions of sodium and potassium ion pump, increase the concentration of sodium ions in lesions and induce cytotoxic edema of cerebral cells.9
Diffusion-weighted imaging demonstrates transient cytotoxic edema involving the corpus callosum in a patient with diffuse brain injury.
As far as the imaging is concerned, the CT scan is considered not sensible enough especially in the initial phases of the disease and a MR scan is warranted in order to detect the scattered (so-called "starfield pattern") or confluent areas of cytotoxic edema caused by the plugging of the cerebral vascular network [19].
In turn, mass effect from vasogenic edema can cause reduced cerebral perfusion leading to ischemia and cytotoxic edema. Cerebral edema is not a well-known complication of intrathecal nonionic contrast material in CT myelograms.
This leads to blood-brain barrier leakage and subsequent cortical and subcortical, predominantly vasogenic, and occasional cytotoxic edema [2].
Cytotoxic edema was identified by a high signal on DWI, which reflects the fluid shift into the intracellular compartment resulting from reduced Na+/K+ ATPase activity.
Cytotoxic edema from intracellular shift of water has been proposed as part of the pathological mechanism of CVT.
A reduced MD suggests cytotoxic edema, whereas an increased MD indicates vasogenic edema [8, 9, 23].
Brain edema is classified into the main pathological processes of cytotoxic edema, in which the prominent feature is the swelling of the cellular elements of the brain parenchyma, and vasogenic edema, in which increased vascular permeability leads to the accumulation of edema fluid in the extracellular spaces [28].
