目的 :了解脊柱结核的 CT表现 ,提高影像诊断与鉴别诊断。方法 :对 32例临床怀疑或平片诊断的脊柱结核进行 CT扫描 ,并分析其表现。结果 :所有病例均经临床及手术病理证实 ,CT表现为椎体及附件骨质破坏 ,椎间盘破坏 ,骨质增生硬化 ,死骨形成 ,椎旁脓肿 ,腰大肌肿胀及椎管受侵。结论 :CT扫描对显示早期隐匿病灶及椎管受侵优于普通 X线平片 ,对脊柱结核的诊断 ,鉴别诊断和指导治疗具有重要意义 Objective: To understand the CT manifestations of spinal tuberculosis, improve the imaging diagnosis and differential diagnosis. Methods: Thirty-two cases of spinal tuberculosis diagnosed by suspected or plain radiofrequency were scanned by CT, and their manifestations were analyzed. Results: All the cases were confirmed by clinical and surgical pathology. The CT manifestations included vertebral body and appendix bone destruction, disc destruction, osteoarthritis, sequestrum formation, paravertebral abscess, psoas swelling and spinal canal invasion. Conclusion: CT scan is superior to plain radiograph in detecting hidden lesions and spinal canal in the early stage, which is of great significance for the diagnosis, differential diagnosis and guidance of spinal tuberculosis
