Case Report : Dicephalic parapagus conjoined twins

Abstract

Dicephalic twins account for around 11% of all conjoined twins. Dicephalic parapagus is an uncommon form of lateral partial twinning characterized by two heads on one trunk. A 25-year-old primigravida was referred to our clinic with a conjoined twin diagnosis, which was made for the first time at 29 weeks of gestation. The fetus had two heads, two separate necks, two vertebrae, a fused heart with two apexes, four ventricles, three atriums, two gastrics, a fused liver, four kidneys (one of which had hydronephrosis and the other concurrent hydroureteric), two bladders, one male gender, two arms, and two legs, according to an ultrasound. A second case is a pair of conjoined twins that were discovered at 20 weeks of gestation and are 29 years old. The results of an ultrasonographic test showed that the fetus has two vertebrae, one heart, one hepar, one umbilical insertion, and one foot with a congenitally equinovarous talus and a rocker bottom. Both pregnancies ended due to family requests for termination and after a conjoined twin committee meeting in our hospital was approved and the unseparable conjoined twin fetus diagnosis was made. The size of two heads necessitated a Caesarean operation.
