Spondylocostal dysostosis (SCD) is a rare congenital disorder that is characterized by vertebral segmentation and formation defects, and asymmetrical rib anomalies. We describe a case diagnosed during the second trimester of pregnancy with the sonographic features of abnormal alignment of the spine, hemivertebrae in the thoracic spine and kyphoscoliosis. Three-dimensional ultrasound demonstrated a 'fan-like' rib cage with fusion of the ribs. The postmortem findings confirmed the ultrasound findings and were consistent with SCD.
脊椎肋骨发育不良（SCD）是一种罕见的先天性疾病，其特征为椎体节段性和形成缺陷以及不对称肋骨异常。我们描述了一例在妊娠中期诊断出的病例，其超声特征为脊柱排列异常、胸椎半椎体和脊柱侧凸。三维超声显示肋骨融合形成“扇形”胸廓。尸检结果证实了超声检查结果，与脊椎肋骨发育不良相符。
