Klippel-Trenaunay syndrome (KTS) is a rare congenital disorder. In this case study, we reported prenatal ultrasound study on a 33-year-old pregnant woman at the gestation of 26 weeks and 3 days, whose fetus was suspected of KTS associated with enlarged right thigh and dilated inferior vena cava. Additionally, we comprehensively reviewed literatures of prenatal KTS published on Medline to further understanding of the prenatal ultrasonographic manifestations of KTS.
