A Case of Prenatally Detected Concomitant Hydrocephalus and Anencephaly in Twin Pregnancy / 대한산부인과학회지

ABSTRACT

Multiple gestation accounts for 1 percent of all pregnancies. But, the morbidity of congenital anomaly is more than 2 times in contrast to singleton gestation. The major congenital anomaly was developed about 2 percent in the multiple gestation. Hydrocephalus and anencephaly, known central nervous system anomaly, were seen about 0.1% each other in singleton gestation. We have experienced a case of prenatally detected concomitant hydrocephalus and anencephaly in twin pregnancy which was diagnosed by ultrasonography at 16 weeks gestation. Thus, we report a case with brief review of the literature.
