Here are some images and videos of agenesis of the corpus callosum in a 29+1 week old fetus of a 18-year-old primigravida with negative anamnesis.

Image 1 and 2: Transverse scans of the fetal head at 30 weeks of pregnancy showing "tear drop" appearance of the dilated lateral cerebral ventricles.

Image 3 and 4: Sagittal gray scale and power Doppler scans at 30 weeks of pregnancy showing abnormal vessel configuration with missing of the classical curve of the pericallosal artery.

Videos 1 and 2: Videosegments show color Doppler sagittal image with pericalosal vessel disarrangement (video 1); and "tear drop" appearance of the dilated lateral cerebral ventricles (video 2).
