Antenatal Sonographic Findings of Agenesis of Corpus Callosum

ABSTRACT Agenesis of the corpus callosum is a central nervous system anomaly that may be associated with other intracranial abnormalities. It is easily diagnosed in the postnatal period by computed tomographic scan and ultrasound. However, its prenatal so-nographic diagnosis remains a challenge. This report will evaluate three cases of fetal agenesis of the corpus callosum, review the antenatal sonographic findings and postnatal outcomes, and provide criteria for the antenatal diagnosis.
