Sonographic diagnosis of conjoined diamniotic monochorionic twins.
According to traditional theories for the pathogenesis of conjoined twins, diamniotic placentation should not occur. We present an unusual case with diamniotic/monochorionic conjoined twins and discuss possible etiologic hypotheses. The diagnosis of this improbable case was made in the first trimester using ultrasound, which assisted in making an early decision regarding further management.
