Syncephalus/Cephalothoracopagus Twins
Cephalothoracopagus is a form of conjoined twinning in which twins are joined at the front from the top of the head to the navel. The head, chest and upper abdomen are fused, while the limbs and pelvis remain separate. Syncephalus describes brain fusion with varying degrees of facial fusion. In the janiceps form, faces develop on opposite sides of the shared head. These may be nearly symmetrical, or one face may be normally formed while the other is small and malformed. Conjoined twinning results from late, incomplete division of an embryo. Cephalothoracopagus occurs in approximately one in three million births. It is nonviable and cannot be separated surgically because of the fused brain and shared organs. Ultrasound can identify the condition before birth. |

Re: Syncephalus/Cephalothoracopagus Twins
If one was a boy and the other a girl, they would've been born in two separate amniotic sacs. The ONLY IDENTICAL TWINS SHARE a birth sac. Male/female twins are fraternal twins. You can have two male twins or two female twins that are not identical, to. They are called fraternal twins, to.
