PY - 2023 T2 - Timor's Ultrasonography of the Prenatal Brain, 4e AB - KEY POINTSAgenesis of the corpus callosum is either complete or limited to the posterior portion; the anatomy is variable but in the complete form the cavum septum pellucidi is not present; in the partial form, findings are more subtle and diagnosis requires direct visualization of the incomplete corpus callosum. The prognosis is largely influenced by the association with other anomalies; isolated agenesis of the corpus callosum may be associated with a normal intellectual development, although the experience is limited.Agenesis of the septum pellucidum is frequently a part of other often severe malformations including holoprosencephaly, gross hydrocephalus, and schizencephaly. Isolated agenesis of the septum pellucidum may be a normal variant, although it may be the only antenatal finding of septo-optic dysplasia, a condition that is usually associated with visual impairment and endocrine dysfunction.
