LASTING CYTOTOXIC EDEMA AS AN INDICATOR OF IRREVERSIBLE BRAIN-DAMAGE - A CASE OF NEONATAL STROKE

We describe a case of neonatal stroke in the territory of the left mid dle cerebral artery. Although the ischemic lesion appeared rather homo geneously hyperintense on T2-weighted MR images, corresponding diffusi on-weighted images clearly delineated two separate zones of different cellular swelling and, thus, different prognoses. Lasting cytotoxic ed ema heralded infarction. We believe that the different rates of disint egration of neurons and glial cells may have caused the change from in tracellular to interstitial volume fraction during the evolution of ed ema.
