Klippel–Trenaunay–Weber syndrome presenting as massive lymphangiohemangioma of the thigh: prenatal diagnosis

We report a case of Klippel–Trenaunay–Weber syndrome presenting prenatally as a massive congenital lymphangiohemangioma of the thigh. Routine ultrasonographic examination revealed multiple distorted cystic areas extending from the right flank through the right lower extremity of a 30‐week fetus. A diagnosis of cystic lymphangioma of the thigh was suspected prenatally. Neonatal evaluation confirmed the prenatal findings. Neonatal color Doppler imaging revealed blood vessels within the tumor. The differential diagnosis is discussed together with available therapeutic procedures. Copyright © 2000 International Society of Ultrasound in Obstetrics and Gynecology
