Three‐dimensional ultrasound findings of spondylocostal dysostosis in the second trimester of pregnancy

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.
