Abstract

60 premature and newborn infants with clinical evidence of hypoxia or traumatic encephalopathy were examined by cranial computerized tomography (CCT) during the first fortnight of life and their findings compared with those of a "control group", consisting of 7 infants with malformations. 48 patients showed pathologic findings in the initial CCT. With regard to type, topography and extension, two groups with two subgroups could be outlined:
1. lesions with low density due to hypoxic-necrotizing alterations. a) Bilateral in the white matter around the frontal and occipital horns of the lateral ventricles in both, premature and fullterm newborn infants. b) Corresponding to vascular distribution, focal or global, involving both gray and white matter in both, premature and newborn infants.
2. lesions with high density due to hemorrhages. a) Subependymal and intraventricular, mainly in asphyxiated premature infants. b) Subdural and intracerebral, probably of traumatic origin, involving premature and fullterm newborn infants.
The morphological findings in the initial CCT were compared with the outcome in each case. Thus, it was possible to distinguish certain morphological patterns significantly associated with prognosis.
14 patients (23.3%) died in the newborn period. The surviving 46 children (76.7%) were at least once re-examined by CCT and followed up during 6-24 months. 16 patients (26.7%) had a normal development. 12 (20%) showed developmental retardation. 18 (30%) suffered from neurological sequela. Frequently the early follow-up CCT showed characteristic patterns. We believe, that the great number of pathologic findings with essential information warrant the application of CCT in premature and fullterm newborn infants with persistent neurological signs. Perhaps our CCT observations will lead to the consequence of a more controlled high care regimen.
