[Cranio-encephalic scanography of the premature infant. Morphogenetic aspects. Radio-anatomical comparisons].

Fifty infants born before 38 weeks of amenorrhea have been studied by computerized tomography. The authors dwell on three points: the malleability of the cranial vault, the normal appearance of the germinal layer before 32 weeks, and the persisting hypodensity of the frontal region. The evolution of the morphology of the subarachoïdian cisterns, of the ventricular system and of the parenchyma are related between 28 weeks and term.
