【摘要】 目的探讨胸肋锁骨肥厚综合征的影像学诊断与鉴别诊断。资料与方法回顾性分析6例患者的X线平片和CT平扫资料。6例中,3例行工作站图像后处理,3例行单光子计算机体层(SPECT)扫描。结果6例均为双侧性胸-肋-锁骨区受累骨增粗,骨、骨髓腔及肋软骨密度增高。相邻关节间隙消失,呈骨性融合。CT见右侧第1肋软骨处假骨折线。SPECT扫描示胸锁关节区双侧较对称的放射性核素浓聚。结论胸肋锁骨肥厚综合征具有较典型的影像学特征,结合临床可做出正确诊断。CT成像在显示受累骨骨皮质、髓腔、韧带骨化、关节骨性强直等方面的改变优于X线平片和SPECT。更多还原

【Abstract】 Objective To improve the imaging diagnosis and differential diagnosis on Sternoostoclavicular hyperostosis syndrome.Materials and Methods Six patients performed plain film and the CT plain scan.Data of three patients were postprocessing reconstructed on work station.Three patients performed SPECT scan.Results CT images of all the involved insternum rib clavicle bones showed thickened,increased density,cavitas medullaris and costal cartilages.The joint spaces ankylosis and were replaced by osteoid tissue.Looser’s bond showed at the first right costal cartilage on CT.On CT axial scan and MPR,the cortical of involved bones showed thickened,increased density due to cavitas medullaris,In addition,ligaments ossification and joint bony ankylosis showed much more clear than plain film,SPECT and the SSD or VR.On SPECT,radionuclide take up on the symmetric areas of bilateral sternoclavicular joints.Conclusion Sternoostoclavicular hyperostosis syndrome had typical clinical imaging features.Combinating with clinical information,it was possible to accurately diagnosis.CT was better than the plain films and SPECT in showing the involved bones on the cortical bone,cavitas medullaris,ligaments ossification and joint bony ankylosis.更多还原
