The parents opted for interruption of the pregnancy.

Images 1-6, videos 1 and 2: 2D images of the fetal head show cranial anatomy dilated lateral ventricles, slightly dilated  third ventricle and all cranial signs of the open spina bifida   - large brainstem (BS), non-visible intracranial translucency, large BS/BSOB ratio (brainstem to occipital bone distance) -, the classic banana sign and small frontomaxillary facial angle , which is characteristic for the first trimester fetuses with open spina bifida.

Images 7-14, videos 3-5: 2D and 3D images in different planes show a bony spur in the lower lumbar region, protruding out from the soft tissues and widening of the spinal canal in the coronal view , which is typical for the diastematomyelia and spina bifida. Image 14 and video 4 show hemivertebra.
