چکیده
Conjoined twins are twins whose bodies are anatomically joined in utero. The degree to which the twins are attached can range from simple, involving skin and cartilage, to complex, including fusion of the skull(s), brain(s), or other vital organs. There are more than a dozen classifications of conjoined twins [3] but what they all tend to have in common is the sharing of the chorion [4], placenta [5], and amniotic sac [6].
