Elongation of the anterior tubercle of a transverse process of a cervical vertebra is a congenital anomaly that should be considered in a patient demonstrating a bony mass projecting anterior to the vertebral body on a lateral radiograph of the cervical spine. Reported is a case of elongation of the tubercles of the transverse processes of both C5 and C6 with the formation of an articulation. Computed tomography was used to definitively differentiate this variant from a fracture fragment, bone tumor, or osteophyte. This anomaly is probably a form of supernumerary cervical rib developing at a level above the lowest cervical vertebra.
颈椎横突前结节延长是一种先天性异常，对于颈椎侧位X线片显示椎体前方有骨性肿块的患者应考虑这一情况。本文报告1例C5和C6横突结节延长并形成关节的病例。采用计算机断层扫描将此变异与骨折碎片、骨肿瘤或骨赘明确区分开来。这种异常可能是最低颈椎上方水平发育的额外颈椎肋骨的一种形式。
