Periventricular Leukomalacia (PVL)
This stock medical exhibit shows periventricular leukomalacia (PVL). The first illustration shows an anterior view of a baby with a heart and a coronal section of the brain ghosted within. The second illustration is an enlarged coronal view of the brain, showing the watershed zone in the brain, as well as white matter, ventricles, the middle cerebral artery and its terminal branches. The third illustration shows ischemia in the watershed zone, including multicystic areas and the site of brain cells dying. The fourth illustration shows the result of the ischemia, which is decreased volume of white matter due to death of brain cells.
