Ultrasonographic Findings of Facial Dysmorphism in Wolf-Hirschhorn Syndrome

ABSTRACT

Wolf-Hirschhorn syndrome has characteristic craniofacial dysmorphism with severe fetal growth restriction. We present a case that revealed facial dysmorphism characteristic of Wolf-Hirschhorn syndrome with two- and three-dimensional ultrasonography. The facial dysmorphic features in the present case were dolichocephaly; high forehead; large rectangular nose continuing to the eyebrows; hypertelorism; short philtrum; carp-shaped mouth; microretrognathia; and large, simply modeled, low-set ears. Chromosome analysis of amniotic fluid cells was 46,XX,del(4)(p15.2), confirming the ultrasonographic result. Examination with two- and three-dimensional ultrasonography is useful to observe the face of fetuses with severe intrauterine growth restriction to diagnose multiple congenital anomaly syndromes.
