摘　　要：目的探讨64排螺旋CT及其后处理技术对SAPHO综合征的诊断。方法观察分析5例SAPHO患者64排螺旋CT平扫及多平面重建、曲面重建、表面遮盖显示、容积再现图像。结果5例SAPHO患者出现双侧锁骨近中段、第1肋骨近端及胸骨膨大。骨质增生硬化，胸一肋一锁关节面侵蚀、硬化、韧带骨化、关节间隙狭窄或骨性融合；3例患者胸椎、腰椎、颈椎表现为椎角骨质侵蚀硬化、椎间隙变窄、骨硬化、椎旁韧带骨化；2例患者发生单侧骶髂关节炎，骶髂关节髂骨面硬化，骶髂关节间隙变窄。结论64排螺旋cT平扫及后处理技术可以良好地显示SAPHO患者胸肋锁骨区、脊柱及骶髂关节的骨炎、骨肥厚、滑膜炎的特征性改变．对SAPHO综合征诊断具有较高的应用价值。Objective To investigate the diagnostic value of 64-slice spiral CT and image post-processing technique for synovitis, acne,pustulosis,hyperostosis and osteitis（SAPHO} syndrome. Methods Five cases with SAPHO syndrome were scanned with 64- slice CT,and raw data of all the patients were processed by using the techniques of multi-planar reformation （MPR）, curve planar reformation （CPR）, surface shaded display （SSD）and volume rendering （VR）. Results All five patients had selerosis,hyperostosis, and bone hypertrophy of medial ends of the bilateral clavicle and first rib. All patients showed erosions of sternocostoclavicular joint, sclerosis,hyperostosis, ligamentous ossification, joint space narrowing, or ankylosis. Three patients had thoracic, lumbar, and cer- vical vertebral body corner lesions, narrowed adjacent disc spaces,osteosclerosis, and paravertebral ossifications. Two patients had sclerosis and hyperostosis on the iliac side of the unilateral sacroiliac joint, with narrowing of the sacroiliac joint space. Conclusion 64-slice spiral CT and image post-processing technique can accurately demonstrate hyperostosis,osteitis, and synovitis in the sterno- costoclavlcular regions, spine, and sacroiliac joint, providing high application value for the diagnosis of SAPHO syndrome.
