Fetal brain imaging, including ultrasound, plays a vital role in the prenatal diagnosis of agenesis of the corpus callosum. Ultrasound uses high-frequency sound waves to create real-time images of the developing fetus, allowing healthcare professionals to visualize the brain and assess its development. 

During ultrasound examinations, specific markers can indicate the presence of agenesis of the corpus callosum. These include a “teardrop” appearance of the lateral ventricles or a “splaying” of the falx, the membrane that separates the two hemispheres of the brain. These findings, along with other measurable parameters, aid in the accurate diagnosis of this condition. 

By detecting agenesis of the corpus callosum early on, ultrasound provides healthcare professionals with valuable information for appropriate counseling, management, and support for expectant parents. This allows them to make informed decisions regarding the future care of their child.
