Abstract

Spondylocostal dysostosis is a rare congenital disorder characterized by multiple vertebral segmentation anomalies and rib malformations, often resulting in thoracic deformity and scoliosis. We report the case of a newborn presenting with thoracic deformity, investigated by thoracic computed tomography (CT). Imaging revealed bilateral costotransverse synostosis involving multiple ribs, associated with vertebral malformations including butterfly vertebrae at D4 and D5, a single right hemivertebra at D2, and dorsal scoliosis with right convexity. No associated pulmonary, mediastinal, abdominal, or suspicious osseous lesions were identified. CT imaging allowed comprehensive assessment of the costovertebral anomalies and exclusion of associated complications. This case highlights the key radiological features of spondylocostal dysostosis and emphasizes the crucial role of CT in diagnosis, anatomical mapping, and early management planning.
