Abstract

Congenital anomalies occur in 2-3% of neonates and have unknown and variable causes. It's occurance rate is higher in twin gestations than in singleton gestations, especially in monozygotic twins. In most cases of twin anomalies, one fetus is normal and the other fetus is not. When an anomaly is found in one fetus, various tests, such as chorionic villus sampling, amniocentesis, and umbilical cord aspiration are strongly recommended in high risk groups of chromosmal anomaly for accurate diagnosis and proper treatments. A case of congenital anomalies in both twins diagnosed in a 35 year old multiparous woman is presented with brief review of literatures.
