Four-vessel umbilical cord with two arteries and two veins, and fetal intra-abdominal umbilical vein varix are rare fetal vascular pathologies, associated with congenital anomalies and an adverse perinatal outcome, respectively. We report a case of a healthy male neonate born at a gestational age of 38 weeks, five days, after prenatal sonographic diagnosis of a four-vessel umbilical cord with a supernumerary vein varix. To the best of our knowledge, this is the first case with this combination.
