The structure of the corpus callosum is eventually formed at approximately 20 weeks gestation [13]. It should be noted that the corpus callosum develops together with related areas of the brain and continues to increase in volume after birth [13,14].
Can the corpus callosum develop after 20 weeks?
The corpus callosum (CC) is the largest commissural pathway connecting the two cerebral hemispheres. It develops relatively late during cerebral ontogenesis, not assuming its definitive shape until 20 weeks of gestation, and continues to grow well after delivery1.
Can you see corpus callosum on ultrasound?
Ultrasonography can identify agenesis of the corpus callosum (excluding holoprosencephaly which an be detected earlier on) in the second trimester of pregnancy (18-20 weeks gestation). Diagnosis of corpus callosum agenesis is difficult but is important as a risk factor for neurological or genetic malformations.
