Periventricular leukomalacia classification

One of the methods used for grading of periventricular leukomalacia based on sonographic appearances is as:

  • grade 1: areas of increased periventricular echogenicity without any cyst formation persisting for more than 7 days
  • grade 2: the echogenicity has resolved into small periventricular cysts
  • grade 3: areas of increased periventricular echogenicity, that develop into extensive periventricular cysts in the occipital and frontoparietal region
  • grade 4: areas of increased periventricular echogenicity in the deep white matter developing into extensive subcortical cysts
