Computed tomographic findings in full-term infants with good prognosis.
To determine the normal neonatal computed tomographic (CT) findings, 121 CT scans of term infants with some neurological symptoms in the neonatal periods and a later good prognosis were studied. The majority of the neonates had asymmetric skulls with backward protrusion of the left occipital bone. In early neonates, the ventricles were small and straight high density lines were commonly seen in the posterior longitudinal cerebral fissure. In many, the left posterior horn was larger than the right one. Periventricular low density areas in the anterior and the posterior horns were noticed. The basal ganglia and the thalamus showed homogeneous density that was the same as that of the cerebellum. About one-third of the neonates had extra-cerebellar low density areas.
