Abstract：
This technical report illustrates the technique to perform computed tomography (CT)-guided bone biopsies in the body and dens of the axis (C2 vertebra) through a posterior transpedicular approach with the use of preoperative contrast-enhanced scans to highlight the course of the vertebral artery. The technique is presented through two exemplification cases: a pediatric patient with osteoblastoma and secondary aneurysmal bone cyst and one adult patient with melanoma metastasis. This case highlights the potential of the CT-guided posterolateral/transpedicular approach for performing safe and effective biopsies in the body and dens of C2, even in pediatric patients.
摘要：
该技术报告说明了通过后路经椎弓根入路在身体和轴（C2椎骨）的腔内进行计算机断层扫描（CT）引导的骨活检的技术，并使用术前对比增强扫描来突出椎动脉的过程。该技术通过两个示例案例介绍：一名患有成骨细胞瘤和继发性动脉瘤性骨囊肿的儿科患者和一名患有黑色素瘤转移的成年患者。这种情况突出了CT引导的后外侧/经椎弓根入路在C2的身体和窝中进行安全有效的活检的潜力，即使在儿科患者中也是如此。
