다국어 초록 (Multilingual Abstract)

The prenatal diagnosis of spine bifida include the combined use of maternal serum α-fetoprotein (MSAFP) screening and fetal sonography. Sonographically, spina bifida is characterized by direct signs of the visualization of the spinal defect, and indirect signs of the cranial markers : the lemon sign, the banana sign, and ventriculomegaly. These ultrasonographic signs are more accurate in defining the cranial malformations associated with spina bifida than evaluation of the spine.
Recently, three cases of spina bifida which was diagnosed as splaying of the posterior ossification centers, meningomyelocele sac at the lumbosacral area, lemon sign, banana sign and ventriculomegaly by ultrasonography at 21+2 gestational weeks in a 32 years old nullipara, at 21+2 gestational weeks in a 26 years old nullipara, at 23+6 gestational weeks in a 26 years old multipara were experienced at our department.
