A 16-year-old woman (G1P0) with non-contributive history was sent to our office at 22 weeks of gestational age due to "fetal hydrocephalus". Our examination revealed the primary cause of the cerebral ventricular dilatation - thoraco-lumbar spina bifida aperta.
Here are some of the images that we obtained.
Images 1, 2
: 22 weeks of gestational age; Images show transverse scan of the fetal head at the level of abnormally shaped cerebellum "banana sign" - depicted in blue on the image 2.
: 22 weeks of gestational age; the image shows transverse scan of the fetal head with dilated lateral cerebral ventricles.
Images 4, 5, and 6
: 22 weeks of gestational age; images show coronal (images 4, 5) and sagittal (image 6) scans of the fetal spine at the level of the lumbar spina bifida.
Images 7, 8
: 22 weeks of gestational age; 3D transverse scans of the fetal head showing dilated lateral cerebral ventricles.
Images 9, 10, 11, 12, and 13
: 22 weeks of gestational age; the images show detailed 3D view of the spinal defect at the level of the thoraco-lumbar spina bifida (the spinal defect is labeled by red arrows on the image 10; normal vertebrae are labeled by green arrows). The image 12 represents a fusion of the image 11 with a drawing depicting approximal position of the thoraco-lumbar spinal defect. The images are adjusted using the MagiCut function of the machine.
Images 14, 15, 16, and 17
: 22 weeks of gestational age; the images show 3D image of the lumbar spina bifida using the classical 3D render mode (images 14, 15) and the VCI-Omni View Acquisition (images 16, 17).
