To investigate the relationship of mild-to-moderate simple bilateral fetal ventriculomegaly with postnatal neurological development.Cases of simple lateral ventricular dilatation (273) were divided into bilateral mild dilatation (10.0-12.0 mm, 62), bilateral moderate dilatation (12.1-15.0 mm, 29), unilateral mild dilatation (133), and unilateral moderate dilatation (49) groups. The control group comprised 50 normal fetuses. Neurological development was assessed using Gesell Developmental Schedules (GDS) at postnatal 3, 6, 12, and 18 months.At postnatal 6, 12, and 18 months, the GDS score was higher for bilateral than for unilateral dilatation (At postnatal month 6, the GDS evaluation results of the bilateral dilatation groups were significantly inferior compared to those of the unilateral dilatation group.
