It is a sign; when diagnosed, a search for all underlying causes should be immediately undertaken.Ventriculomegaly is frequently associated with a significant number of intra- and extracranial chromosomal as well as nonchromosomal anomalies as well as microarray abnormalities.For measuring the lateral ventricle, it is recommended to use an axial view of the brain and to place the calipers at the level of the parieto-occipital fissure that is usually well demonstrated from 20 weeks’ gestation.Congenital ventriculomegaly has an increased recurrence rate and after the birth of an affected infant a targeted neuroscan is recommended in a subsequent pregnancy.
