Case report


A 29-year-old woman (G2P1) with non-contributive history was sent to our office at 20 weeks, 3 days of gestational age due to high levels af the AFP in maternal serum. Our examination small occipital defect with a tail-like meningocele combined with agenesis of the corpus callosum. The parents opted for the termination of the pregnancy.

Here are some of the images that we obtained.

Images 1,  2, 3, and 4: 20 weeks, 3 days gestational age; the images 1-3 show transverse scan of the fetal head at the level of abnormally shaped lateral cerebral ventricles - tear drop appearance (colpocephaly) with absent cavum septi pellucidi. The image 4 shows absence of the corpus callosum in sagittal plane of the fetal head.

 

 

Image 5: 20 weeks, 3 days gestational age; the image shows small occipital defect (4.2 mm) with a small tail-like meningocele.



Images 6,7, 8, 9, and 10: 20 weeks, 3 days gestational age; the images show 3D appearance of the tail-like looking occipital meningocele - arrows on image 7, 9, and 10. Images 6, 7 - classical 3D images; images 8, 9 - HDlive imaging; image 10 - glass body imaging.

 





Videos 1, 2,  3, and 4: 20 weeks, 3 days gestational age; the videos show rotational 3D sequences of the fetal head showing the appearance of the tail-like looking occipital meningocele depicted in various 3D modes. Videos 1, 2 - classical 3D mode; videos 3, and 4 - glass body imaging.
