The search for all underlying causes should be immediately undertaken.Ventriculomegaly is frequently associated with a large number of intra- and extracranial chromosomal as well as nonchromosomal anomalies.For measuring the lateral ventricle it is recommended to use an axial view of the brain and to place the clipers at the level of the parieto-occipital fissure that is usually well demonstrated from 20 weeks' gestation.Congenital ventriculomegaly has a increased recurrence rate and after the birth of an affected infant a targeted neurscan is recommended in a subsequent pregnancy.
