Sonographic finding of ventricular asymmetry in neonatal brain

Abstract

One thousand normal Chinese full term neonates underwent prospective ultrasonography examination. Asymmetry of size between the right and left lateral ventricle was observed in a similar proportion of boys: 257/551 (47%) and girls: 183/449 (41%). The mode of delivery did not significantly influence the occurrence of ventricular asymmetry. We propose four different patterns of asymmetry.
