To evaluate the value of prenatal ultrasonographic diagnosis of diastematomyelia, and to provide a basis for the diagnosis and differential diagnosis of fetal diastematomyelia.
Four fetuses with suspected diastematomyelia based on prenatal ultrasonography are presented. Detailed prenatal ultrasonography was performed to examine spinal cord abnormalities. The region of interest-based spine sagittal plane was defined and 3D volumetric scans were performed, as needed. Images were stored and compared with MRI or ultrasonographic images after abortion.
In the four cases of diastematomyelia diagnosed by prenatal ultrasonography, two were confirmed by MRI after birth, and the other two were confirmed by autopsy and pathologic examination after abortion. Varying degrees of spine or spinal cord deformities were noted. Two pregnancies were terminated, and two newborns underwent surgery.
Prenatal ultrasonography contributes to the diagnosis of diastematomyelia and provides a basis for prenatal counseling and prognosis.
评估产前超声诊断脊髓纵裂的价值，为胎儿脊髓纵裂的诊断及鉴别诊断提供依据。
介绍4例产前超声怀疑为脊髓纵裂的胎儿。进行详细的产前超声检查以检测脊髓异常。根据需要定义基于感兴趣区域的脊柱矢状面并进行三维容积扫描。图像被存储，并与流产后的MRI或超声图像进行比较。
在产前超声诊断为脊髓纵裂的4例病例中，2例出生后经MRI证实，另外2例流产后经尸检及病理检查证实。观察到不同程度的脊柱或脊髓畸形。2例妊娠终止，2例新生儿接受了手术。
产前超声有助于脊髓纵裂的诊断，并为产前咨询及预后提供依据。
