目的：探讨脊柱结核骨破坏类型及CT表现特征。材料与方法：回顾性分析40例脊柱结核的CT表现。结果：4种骨破坏类型中粉碎型最常见（33．3％），溶骨型28．4％，骨膜下型18．5％，局灶硬化型19．8％。附件及肋骨破坏发生率分别为34．6％和25％，椎间盘破坏占40％，椎旁软组织肿出现率为80％，且波及范围广（平均3．5个椎体），硬膜外脓肿出现率为40％，椎管内碎骨块达27．5％。结论：粉碎型骨破坏是脊柱结核最具特征的CT表现，而局处性骨硬化伴死骨形成，椎体骨破坏伴椎旁软组织肿块内出现骨碎块或钙化也是脊柱结核比较特征的CT表现。
Objective: To investigate the types of bone destruction and CT features of spinal tuberculosis. Materials and Methods: The CT findings of 40 cases of spinal tuberculosis were retrospectively analyzed. Results: Among the four bone destruction types, the most common type was crushed (33.3%), the osteolytic type was 28.4%, the subperiosteal type was 18.5% and the focal sclerosis was 19.8%. The incidence of appendages and rib destruction were 34.6% and 25%, respectively, with disruption of the disc 40% and paravertebral soft tissue mass 80% with a wide range of spreads (average 3.5 vertebral bodies), epidural abscess Occurrence rate was 40%, spinal bone fragments reached 27.5%. Conclusion: Crushed bone destruction is the most characteristic CT manifestations of spinal tuberculosis, and local sclerosis with the formation of dead bone, vertebral bone destruction with paravertebral soft tissue mass within the bone fragments or calcification is more characteristic of the spinal tuberculosis CT which performed.
