[Craniorachischisis in conjoined "diprosopus" twins. Case report and review of the literature].
The pathological features in a case of craniorachischisis with incomplete twinning (diprosopus) are reported. The female fetus was born to a 27-year-old gravida 6, para 3 healthy woman who underwent a medical abortion at 13 week's gestation because of an anencephaly revealed by ultrasound examination. The head showed two fused faces with two mouths, two noses, two lateral completely formed eyes and two medially fused eyes covered by cutaneous tissue. X-ray examination demonstrated the symmetrically doubled spinal column. The brain and the spinal cord were absent (craniorachischisis). The larynx and the oesophagus, the other viscera and the limbs were normal in number, location and morphology as for a female singleton. This case with others from the literature, illustrates the relationship between conjoined twinning, neural tube defects (more particularly anencephaly) and female zygote and constitutes a real entity.
