Congenital cervicothoracic spondyloptosis in a 7-month-old patient

Abstract

A 7-month-old patient presented with cervicothoracic bulge recognized by the parents. Cervicothoracic computed tomography and magnetic resonance imaging were performed to demonstrate the pathology. Distinct anterior displacement and inferior slippage of cervical vertebral block over subjacent thoracic vertebrae, impaction of the thoracic vertebral block into the enlarged cervical spinal canal, and multilevel posterior fusion defects throughout the cervical vertebrae were seen in his CT images (Fig. 1). Spinal cord was angulated and thickened at the level of impaction by the thoracic vertebral block, and there were irregularity and increased focal nodular signal intensity in the anterior part of the distal
