BACKGROUND
Diastematomyelia and diplomyelia are rare form of spinal cord malformations (SCM) characterized by sagittal cleft in the spinal cord, conus medullaris, and/or filum terminale with splaying of the posterior vertebral elements and duplication of the spinal cord into two twin cords. Prenatal diagnosis of these diseases by two-dimensional ultrasound has been reported usually late in pregnancy and only recently in the first trimester.
OBJECTIVE
We describe the first case of cervico-thoracic diastematomyelia and diplomyelia diagnosed early in pregnancy using three-dimensional ultrasound.
背景
脊髓纵裂和脊髓重复畸形是脊髓畸形（SCM）的罕见形式，其特征为脊髓、脊髓圆锥和/或终丝矢状裂，伴有后方椎体结构分离以及脊髓分裂为两条双脊髓。二维超声对这些疾病的产前诊断通常在妊娠晚期报道，最近才在孕早期报道。
目的
我们描述了首例使用三维超声在孕早期诊断的颈胸段脊髓纵裂和脊髓重复畸形病例。
