Periventricular leukomalacia occurs at the age group between 28 and 34 weeks of gestation [15] and it is due to an ischaemic process along the watershed zone in the periventricular white matter.
Of these, 4,725 term-born neonates (including twins) were evaluated (50.8% male and 49.2% female), in 61 (100%) of which white matter damage (WMD) was detected (lateral ventricle enlargement (n = 57/61; 93%), lateral ventricle asymmetry (n = 29/61; 48%), bilateral enlargement of the lateral ventricle (n = 29/61; 48%), posthemorrhagic hydrocephalus (n = 3/61; 5%), diffuse periventricular leukomalacia (n = 2/61; 3%), cystic periventricular leukomalacia (porencephaly) (n = 0/61; 0%)) (Table 1) with no gender-related differences in the overall rate of white matter damage (male 1.4% versus female 1.2%, n.s.).

The major neonatal complications that affect later development remain preterm brain injury (intraventricular hemorrhage or periventricular leukomalacia), chronic lung disease, necrotizing enterocolitis, and sepsis.
With cranial ultrasonography, we determined the grade of periventricular leukomalacia (PVL) according to criteria described by Weisglas-Kuperus (14): grade I PVL, prolonged periventricular flare present for 7 days or more; grade II PVL, prolonged periventricular flare with small, localized frontoparietal cysts; grade III PVL, extensive periventricular cystic lesions involving occipital and frontoparietal white matter; grade IV PVL, areas of extensive subcortical cystic lesions.
A major cause is cystic periventricular leukomalacia (cPVL) comprising necrosis and subsequent cyst formation of the periventricular white matter: 60-100% of children with cPVL develop cerebral palsy [4-6].
