Fate of 6 Fetuses with Ventriculo-Megaly or Potential Ventriculo-Megaly Followed Up Post-Natally

Abstract Six fetuses were studied - 3 with ventriculomegaly and normal head circumferences, 2 with ventriculo-megaly and enlarged head circumferences, and 1 with a Dandy-Walker complex and normal lateral and third ventricles. Post-natally it was found that fetal ventriculo-megaly was not associated with raised intracranial pressure at least in the first few months of life unless the head size was enlarged. The baby with the Dandy-Walker complex developed ventriculo-megaly and raised intracranial pressure several months after birth following progressive enlargement of the posterior fossa extra-axial cyst.
