GMH-IVH and CPH were considered as primary injuries, and hydrocephaly, cystic periventricular leukomalacias, widened extracranial space, and subependymal cysts were considered as secondary injuries.
In this neonatal ultrasound screening study that is the only available trial in which cranial abnormalities were assessed across the whole range of gestational ages (24-43 weeks gestation), the overall incidence of WMD was 0.02%, 0.02%, and 2.6% for periventricular leukomalacia, porencephaly (cystic periventricular leukomalacia), and enlarged lateral ventricles, respectively [4]; however, only cerebral hemorrhage but not WMD was evaluated.
The various forms of white matter damage, including "lateral ventricle asymmetry," "lateral ventricle enlargement," "lateral ventricle bilateral enlargement" (defined as an enlargement of the lateral ventricle without ventricular asymmetry), "posthemorrhagic hydrocephalus," "diffuse periventricular leukomalacia," and "cystic periventricular leukomalacia (porencephaly)" as observed in individual patients (n = 61) are listed in Table 1.
