Agenesis of the corpus callosum

Case contributed by Dr Praveen Jha


Antenatal check-up (at 39 weeks of gestation). Patient was having regular antenatal ultrasound at some other place, however no gross abnormality was detected earlier.

Patient Data

Age: 39 Weeks
Gender: Female

Sonographic visibility is compromised due to mature skull at 39 weeks.

Dilated occipital horns of lateral ventricles is seen with parallel appearance of bilateral lateral ventricles. Sagittal images could not show corpus callosum properly. Patient was advised for a post-natal MRI.


Post-natal MRI confirms the findings of corpus callosum agenesis. 

Case Discussion

Colpocephaly is frequently associated with partial or complete corpus callosal agenesis. Although, visualization of corpus callosum may be difficult in obstetric scans, ventricular trigones and orientation of ventricles is well visible. This may be a useful pointer to the associated anomaly.
