RESUMO
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.

Our purpose was to evaluate the clinical significance of large (>5cm) placental chorioangioma. Obstetrical and neonatal records which were confirmed chorioangioma in pathology and greater than 5 cm in diameter, were reviewed retrospectively from April. 1, 1991, to March. 31, 1996. 11 cases of placental chorioangioma greater than 5 cm were diagnosed prenatally by ultrasonography except one. I'hey were associated with maternal or fetal complications-6 cases of polyhydramnios, 2 cases of PIH, 1 case of neonatal anemia, 2 cases of preterm birth, 2 cases of neonatal hyperbilirubinemia, 1 case of cardiomegaly, 1 case of IUGR and 1 case of oligohydramnios. Nevertheless, there were not remarkable neonatal morbidity and mortality. These uncommon large tumors were often associated with maternal or fetal complications. But, we could get good neonatal outcome through thorough antenatal surveillance.
