Fetal central nervous system malformations are commonly encountered during routine fetal morphology scans. Fetal ventriculomegaly is among the most common prenatal neuroimaging findings including midline abnormalities, posterior fossa abnormalities, and cortical malformation. Their imaging features are often symptoms or part of the phenotypic features of the underlying disease. Collective information from targeted fetal neurosonography, magnetic resonance imaging, and genetic testing can help clinicians to make the diagnosis. We review various common and essential fetal neuroimaging features and highlight their association with inborn errors of metabolism.
