Sonographic Appearance of Klippel-Trénaunay-Weber Syndrome Diagnosed at 18 Weeks Gestation

Abstract

Presented is a case of Klippel-Trénaunay-Weber (KTW) syndrome. This rare syndrome is associated with a triad of anomalies including varicose veins, cutaneous hemangiomas, and bony or soft tissue hypertrophy. The prominent sonographic finding is multiple cystic areas or localized edema most often located on the lower torso of the fetus. Findings suggestive of KTW syndrome were noted following an 18-week gestation fetal survey and were later confirmed at autopsy.
