Sonographic Identification of Klippel-Trenaunay-Weber Syndrome

Abstract

Klippel-Trenaunay-Weber syndrome is a rare cutaneous vascular disorder characterized by the presence of multiple hemangiomata, arteriovenous fistulas, and limb hypertrophy. We report the prenatal sonographic findings in a case of Klippel-Trenaunay-Weber (KTW) syndrome including fetal limb hypertrophy and large subcutaneous cystic lesions. Prenatal diagnosis is possible by ultrasound examination and recognition important for prevention of complications and future management.
