Umbilical cord cysts are important due to their association with fetal chromosomal abnormalities and fetal structural defects and in case of their rapid growth of umbilical cord cysts they are associated with compression of umbilical vessels and fetal distress. In this article we aimed to present a case with two umbilical cord cysts detected by ultrasonography at 31 weeks of gestation and who had delivered a healthy male fetus by cesarean section at 37 weeks of gestation. Histopathological examination of placenta and umbilical cord after birth revealed that cysts were true allantoic cysts. An additional urachal pathology and anomaly was not observed and the newborn was discharged after primary excision. As a result, we think that ultrasound examination of umbilical cord should be an important and routine part of obstetric ultrasonography
