FATE OF 6 FETUSES WITH VENTRICULO-MEGALY OR POTENTIAL VENTRICULO-MEGALY FOLLOWED UP POSTNATALLY

Six fetuses were studied - 3 with ventriculo-megaly and normal head ci rcumferences, 2 with ventriculo-megaly and enlarged head circumference s, and 1 with a Dandy-Walker complex and normal lateral and third vent ricles. Post-natally it was found that fetal ventriculo-megaly was not associated with raised intracranial pressure at least in the first fe w months of life unless the head size was enlarged. The baby with the Dandy-Walker complex developed ventriculo-megaly and raised intracrani al pressure several months after birth following progressive enlargeme nt of the posterior fossa extra-axial cyst.
