One of the methods used for grading periventricular leukomalacia on sonographic appearance is as follows: grade 1: areas of increased periventricular echogenicity without any cyst formation persisting for more than 7 days. Around the foci is generally defined area of other lesions of the brain white matter - the death of prooligodendrocytes, proliferation mikrogliocytes and astrocytes, swelling, bleeding, loss of capillaries, and others (the so-called "diffuse component PVL"). 2003 Mar;105(3):209-16. doi: 10.1007/s00401-002-0633-6.

Periventricular leukomalacia (PVL) is characterized by the death or damage and softening of the white matter, the inner part of the brain that transmits information between the nerve cells and the spinal cord, as well as from one part of the brain to another. 3. Reperfusion of ischemic tissue is associated with vascular injury, increased reactive oxygen and nitrogen species production, and abnormal inflammation5,8. Infants with PVL often exhibit decreased abilities to maintain a steady gaze on a fixed object and create coordinated eye movements. The white matter in the periventricular regions is involved heavily in motor control, and so individuals with PVL often exhibit motor problems.

[11] These cytokines are toxic to the developing brain, and their activity in an effort to respond to specific areas of damaged tissue is believed to cause "bystander damage" to nearby areas that were not affected by the original insult. A 2007 article by Miller, et al., provides evidence that white-matter injury is not a condition limited to premature infants: full-term infants with congenital heart diseases also exhibit a "strikingly high incidence of white-matter injury.
