【摘要】 目的:研究脊柱化脓性感染的MRI征象,提高诊断准确性。方法:回顾性分析19例手术病理证实的脊柱化脓性感染患者的临床和MRI资料,对椎体和椎间盘改变、椎旁脓肿、椎管内硬膜外脓肿的MRI表现和脊柱韧带是否受累进行分析评价。结果:19例患者共32个椎体发病,颈椎4例,胸椎2例,腰椎13例。化脓性脊椎炎6例,化脓性椎间盘炎8例,化脓性脊椎炎和椎间盘炎合并存在5例,继发硬膜外脓肿9例。MRI对病变定性诊断17例(占89.5%)与病理结果一致,硬膜外脓肿、脊髓受压的程度和脊柱韧带的破坏术前评估和术后手术结果基本一致。结论:MRI对于显示脊柱化脓性感染的病变范围和定性诊断的准确性很高,一般可以准确诊断。更多还原

【Abstract】 Objective:The purpose of this study is to evaluate the MRI findings of pyogenic infection in spine and improve the diagnosis accuracy.Methods:Retrospective analysis was made of the MRI and surgery findings of 19 patients with pathologically confirmed pyogenic infection in spine.Before operation,MRI plain scan was carried out in all cases and Gd-DTPA enhanced scanning was performed in 9 cases.Results:Of 19 cases,32 vertebral bodies were involved.The lesions developed at lumbar spines in 13 cases,thoracic spines in 2 and cervical spines in 4.Six cases were pyogenic spondylitis,8 cases were pyogenic discitis.Pyogenic spondylitis affiliated with pyogenic discitis occurred in 5 cases.9 cases had secondary epidural abscess.The qualitation diagnosis of MRI was identical with pathological diagnosis in 17 (89.5%) cases.The MRI preoperative appraisals about epidural abscess,compression of spinal cord and vertebral column ligaments destruction all accorded with the operation findings.Conclusion:MRI is sensitive and accurate in the diagnosis of pyogenic infection in spine.According to the MRI findings,we can make a definite diagnosis after careful discrimination.更多还原
