Turner syndrome is the most common sex chromosome abnormality in fetus and is characterized by a partial or complex X monosomy. Only approximately 1 percent of fetuses with 45,X survive to term and Turner syndrome has been confirmed in 15 percent of the first trimester miscarriages. Congenital anomalies are detected by sonographic examination in 60-70% of the prenatally diagnosed Turner syndrome and the majority are detected at second trimester. Typical prenatal sonographic findings are nuchal cystic hygroma, fetal hydrops, lymphedema, cardiac and renal anomalies. We present a case of Turner syndrome confirmed by chromosomal study after delivery, in which fetal feet edema was identified without other anomalies during the second trimester sonographic examination.
