脊柱结核骨破坏类型及CT表现特征

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。

Patterns of Bone Destruction and CT Feature in Spinal Tuberculosis

Purpose: To evaluate the patterns of bone destruction and CT feature in spinal tuberculosis. Materials and Methods: A retrospective analysis was performed of CT manifestation of 40 cases with spinal tuberculosis. Results: Four patterns of bone destruction were noted. The fragmentary bone destruction was most common (33. 3% ), osteolytic type was 28. 4%,subperiosteal was 18. 5%, localized sclerotic margins type 19. 8%. The incidence of involvement of vertebral appendage and rib were individual 34. 6%and 25%. intervertebral disc destruction was 40%. soft-tissue masses was hisher (80%). the longitudial extent of the soft -tissuc masscs was always singificantly greater than the length of vertebral involvement (mean 3. 5vertebral lengths). Epidural abscess was seen in 40%. Bone fragments of the spinal canal were detected in 27. 5% cases. Conclusion: the most characteristic and frequent type of bone destruction seen in this paper was the fragmentary typc. localized bone sclerotic type with sequestrum and verterbal bone destrution with fragmentary bone or calcification in the paravertebral soft-tissue masses also were the characteristic CT manifestation of spinal tuberculosis
