[Ultrasound diagnosis of four fetuses with Fraser syndrome during pregnancy].

The authors present results of sonography analysis of four fetuses with Fraser syndrome. First woman had prenatal diagnosis by ultrasounds and ascites of fetus with polyhydramnion were diagnosed in two of her successive pregnancies. The second pregnant woman was observed by ultrasound and lack of kidney was detected. The third pregnant one was diagnosed at first trimester of pregnancy and results of sonography examination were at norm. After delivery, Fraser syndrome in all of these children was diagnosed. Findings on sonography included: ascites of fetus, polyhydramnion, hydrocephalus and nonvisualization of kidney. Sonography is more efficient in the diagnosis of Fraser syndrome in a fetus whose parents had had a previous affected child because of diverse anomalies were observed.
