Prenatal diagnosis of severe congenital malformations associated with elevated amniotic fluid alpha-feto protein

Two cases of severely malformed infants with abnormal fetal images on B-scan sonography and markedly elevated amniotic fluid AFP are presented. There was no evidence of neural tube anomalies. The importance of an amniocentesis and AFP in pregnancies with an abnormal fetal image on B-scan sonography is emphasized, taking into consideration that most pregnancies with elevated fluid AFP have serious fetal anomalies.
