Antenatal Hydrops Fetalis with Umbilical Vein Varix and Thrombosis - Ultrasound Imaging: A Rare Case.

Thrombosis of the umbilical vein/artery is a rare complication and is highly associated with fetal mortality. Varix of the fetal umbilical vein is a very rare anomaly and refers to the focal dilatation of the umbilical vein of the fetus. It appears as a round or fusiform cystic structure in the fetal abdomen. Here, in this case report, we hereby discuss a 28-year-old pregnant female with a gestational age of 26 weeks from last menstrual period, who on antenatal ultrasound had findings suggestive of umbilical vein varix with thrombosis and hydrops fetalis.
