Two‐ and three‐dimensional sonographic diagnosis of fetal intra‐abdominal umbilical vein varix: A case report

Abstract

Fetal intra-abdominal umbilical vein varix is a rare condition characterized by focal dilatation of the umbilical vein of the fetus. We report a case of fetal intra-abdominal umbilical vein varix associated with additional sonographic abnormalities and detected at 31 weeks' gestation. Several follow-up sonographic examinations were performed, and the prenatal findings were confirmed on postnatal ultrasound. The diagnosis was facilitated by the use of three-dimensional power Doppler sonography.
