Prenatal diagnosis of Klippel-Trenaunay-Weber syndrome: a case report.

At 20 weeks of gestation, a typical combination of a massive enlargement of the right fetal leg and multiple cystic lesions was detected at ultrasound examination. Color-coded Doppler examination revealed no arteriovenous fistulae. These findings allowed an in utero diagnosis of the Klippel-Trenaunay-Weber syndrome, which was confirmed after subsequent termination of the pregnancy. The severe malformation involved the upper and lower right leg. No arteriovenous fistulae were found. Copyright 1992 International Society of Ultrasound in Obstetrics and Gynecology
