Summary
Cerebral white matter lesions seen in the perinatal period include periventricular leukomalacia (PVL), historically defined as focal white matter necrosis, and diffuse cerebral white matter gliosis (DWMG), with which PVL is nearly always associated. The first use of the term PVL was by Banker and Larroche in 1962, although the gross and microscopic features had been noted by others (reviewed in Haynes and Folkerth, 2018 [1]). More recently, the broader terms white matter injury (WMI) or diffuse white matter injury (DWMI) have been in use, in part because it refers to the increasingly more common pattern of DWMG, with or without microscopic necroses, reflecting the trend toward decreasing macroscopically visible (or sonographically detectable) “cystic” lesions. This decrease in perinatal brain injury is in turn attributed to improvements in supportive care of preterm neonates, at especial risk for fluctuations of blood pressure (and often cerebral perfusion pressure), and respiration/oxygenation [2].
