Dilatation of the fetal cerebral ventricles (ventriculomegaly) is a generic sonographic sign common to several pathological entities carrying different prognoses. The main causes of fetal ventriculomegaly are aqueductal stenosis, Chiari II malformation, Dandy-Walker complex and agenesis of the corpus callosum. Ventriculomegaly is easily recognized by ultrasound by measuring the atrial ...
