Diastematomyelia is a rare malformation characterized by complete or incomplete division of the spinal cord by osseous or fibrocartilaginous septum. Most cases are seen in association with other anomalies of the vertebral column such as spina bifida, kyphoscoliosis, butterfly vertebra, and hemivertebra. In this report we describe two cases of isolated diastematomyelia detected at routine second-trimester detailed ultrasound scan, the most striking feature being the detection of an echogenic focus in the posterior aspect of the spine in association with widening of the interpedicular vertebral space. The prenatal literature is reviewed to assess the clinical significance of this finding.
脊髓纵裂是一种罕见的畸形，其特征是脊髓被骨或纤维软骨隔完全或不完全分隔。大多数病例与脊柱的其他异常相关，如脊柱裂、脊柱侧弯、蝴蝶椎和半椎体。在本报告中，我们描述了两例在孕中期常规详细超声扫描时发现的孤立性脊髓纵裂病例，最显著的特征是在脊柱后侧检测到一个强回声灶，同时椎弓根间隙增宽。本文回顾了产前文献，以评估这一发现的临床意义。
