Conjoined twins are a rare phenomenon, occurring in 1% of monochorionic twin gestation, with an incidence of 1 : 50 000 to 1 : 100 000. Many conjoined twins have abnormalities incompatible with life, so early prenatal diagnosis is very important for optimal management of both pregnancy and delivery. We report a case of dicephalus parapagus conjoined twins, sharing a single heart, diagnosed at 12 weeks’ gestation. With early ultrasound diagnosis, we were able to provide appropriate and timely prenatal counseling to the family.

Ultrasound Features

Conjoined twinning occurs in 1/100 of monozygotic twins, 1/50,000 gestations and 1/250,000 live births. It is the consequence of a division event at the primitive streak stage of the human embryonic development, about 13-14 days after fertilisation, in monochorionic monoamniotic gestations. A healthy pregnant woman, Gravida 2 Para 1, was admitted into our Fetal Medicine Unit to perform the first trimester ultrasound. A diagnosis of conjoined parapagus twinning based on ultrasound features was made at 11 weeks of gestation, and the couple decided to terminate the pregnancy. The ultrasound showed two independent skulls and hearts, a shared spine below the thoracic level, and a shared stomach. The pathological findings were slightly different, showing two independent stomachs draining into a common duodenum. The karyotype was 46 XY. Early prenatal ultrasound may provide a window to counsel the family and to offer an early termination of pregnancy.

Sixteen cases of prenatal ultrasound diagnosis of chorionic bump at 6–29 weeks of gestation, as well as an analysis of the literature covering 97 cases of prenatal diagnosis of chorionic bump is presented. All cases of chorionic bump was isolated. In 14 (87.5 %) cases the outcome of pregnancy was favourable, in 2 (12.5 %) cases were poor outcome. Сhorionic bump on first-trimester sonography is not necessarily associated with a guarded prognosis, but it condition is recommended to assign the patient to the high-risk group of a threatened miscarriage and ensure careful dynamic ultrasound observation.

The 2 cases prenatal ultrasound diagnosis of OEIS complex (omphalocele (O) + exstrophy of the cloaca (E) + imperforate anus (I) + spinal defect (S)) in the first trimester are presented. The problems of differential prenatal diagnosis and prognosis, possibility of early diagnostic complex detection are discussed.
