Fetal Isolated Ventriculomegaly: Is There any Neonatal Consequences?

Isolated fetal ventriculomegaly is the most common cerebral anomaly encountered in utero during a routine pregnancy scan. Ultrasonography remains the most easy to access tool in the examination of the fetal brain, although fetal MRI is a more accurate method of evaluating fetal ventriculomegaly— asso ciated brain anomalies are found in 17% of the cases after performing fetal MRI. Amniocentesis with chromosomal evaluation must be performed, because kariotype anomalies are more frequently encountered in fetuses with enlargement of the ventricular atrium, but the ventriculomegaly can be a cosequence of congenital infection with CMV, Toxoplasma or Rubella. Fetal isolated ventriculomegaly is a significant risk factor for developmental delay in children.
