title: Elevated alpha-fetoprotein levels in the 45,x (Turner syndrome) fetus with cystic hygroma. Case reports.
abstract: A 45,X fetus with cystic hygroma, associated with an elevated amniotic alpha-fetoprotein (AFP) level (greater than 80 microgram/ml). Is described, as are macroscopic and microscopic characteristics of this fetus and two other female fetuses with cystic hygroma. The ultrasonographic diagnosis of fetal cystic hygroma is discussed. The association of a high amniotic AFP level with cystic hygroma is considered. The relationship between cystic hygroma and pterygium colli in liveborn infants with Turner syndrome, and the evolution of neck webbing, as seen in the adult with turner syndrome, is also discussed.
