CEREBRAL MALFORMATIONS AGENESIS OF THE CORPUS CALLOSUM AND CAVUM SEPTUM PELLUCIDUM
¢There can be partial or complete absence of the corpus callosum.
— Most often, if the corpus callosum is absent, the cavum septum pellucidum will be absent as well.
— Their nonexistence has been linked to as many as 50 to 200 different syndromes and anomalies, such as holoprosencephaly, Dandy-Walker malformation, aqueductal stenosis, trisomy 18, trisomy 8, and trisomy 13.
¢There are several distinct sonographic findings consistent with agenesis of the corpus callosum, excluding the obvious absence of this structure.
