title: Fetal CNS: a systematic approach.
abstract: Prenatal sonography is routinely used to evaluate fetal biometry and anatomy between 16 and 20 weeks. Ventriculomegaly is easily seen on these routine views and is commonly associated with numerous intracranial anomalies. Although ventriculomegaly can be isolated, it should always prompt a detailed search to evaluate for an underlying cause. Using a systematic approach to evaluate the intracranial structures can help the clinician arrive at a correct diagnosis for many abnormalities of central nervous system.
