title: First trimester diagnosis of dicephalus conjoined twins.
abstract: Dicephalus twinning is an extremely rare type of conjoined twins. Early prenatal diagnosis of this condition is important to provide an opportunity for pregnancy termination. We present such a case, which was diagnosed by ultrasound examination at 12 weeks of gestation. The ultrasonographic criteria are discussed together with implications for management.
