The mechanism of demyelination is not inflammatory, like in multiple sclerosis, but is thought to be due to vasogenic and intramyelinic edema, cerebral dehydration, and oligodendrocyte damage ( …
WebCentral pontine myelinolysis is a concentrated, frequently symmetric, noninflammatory demyelination within the pons. The area involved is usually confined to the basal part of the pons but occasionally involves the tegmentum also. The Pons is situated in the brainstem.
