Dicephalus Parapagus Conjoined Twins Diagnosed by First-Trimester Ultrasound

Abstract EN

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.
