Cranial real-time ultrasound in premature neonates.

Two hundred and seventy-three ultrasound examinations in 140 premature infants were performed with a transportable real-time scanner. Evidence for intracranial pathology was found in 86 (61%) of infants. In 66 infants (47%) a hemorrhage and in 79 infants (56%) ventricular dilatation was present. Choroid plexus larger than 12 mm was suggestive for either a bleeding into or onto the plexus. Cavum septi pellucidi was present in 72% of examined infants.
