Porencephaly and schizencephaly in adopted infants. Frequency ascertainment in a risk group.
A formal inquiry on the health state of 1206 legally adopted children from Indonesia revealed cerebral palsy in 9 (0.9% of 1029 responses obtained), including two who had died. CT examination performed in 7 cases was abnormal in all. Four types of lesions were seen: 1. Bilateral full thickness porencephalies (BFTP lesion) in 4 cases, amounting to 0.4% of the total population on which response was obtained. 2. Full thickness porencephaly of the area of one internal carotid artery in 1 case. 3. Schizencephaly-like lesion in 1 case, confirmed by magnetic resonance imaging. 4. Supratentorial midline cyst resulting in hydrocephalus. The frequency of the BFTP lesion found in 4 out of 7 cerebral palsied investigated by CT is remarkable in view of its rarity in radiological studies on cerebral palsy and because of its relationship to prenatal rather than perinatal damage according to previous pathological studies. This is the first systematic study on the neurodevelopmental outcome of a group of adopted babies which indicates an increased risk to specific prenatal brain damage.
