摘　　要：目的探讨脊髓脓肿的MRI表现,减少误诊率。方法分析现有病例影像学及临床资料并复习文献,总结脊髓脓肿的影像学特征。结果患者初诊MRI显示颈段脊髓及髓外异常信号,增强扫描脊髓内见明显多环状强化,环壁较光整,髓外肿物中等强化。1年后复查MRI显示原髓内病变基本消失,髓外残存小环状明显强化病变,CT示髓内小环状病变通过同水平棘突间隙与皮下相通。结论脊髓脓肿较少见,极易误诊,通过认真分析影像及临床资料有望提高正确诊断率,减少误诊的发生。Objective To discuss the appearances of intramedullary abscess on MRI and improve its diagnostic rate. Methods The imaging and clinical informations of the present case of intramedullary abscess were analysed with review of the literatures. Results In first visit of this patient, the abnormal signals were found in the cervical cord and extramedullary tissue,and multiple circular enhancements with smooth margins were found in intramedullary tissue, the extramedullary lesions were also moderately enhanced. One year later, MRI found that the intramedullary lesion was disappeared, but the extramedullary lesion was marked enhanced. A small circular lesion in spinal cord communicated with subcutaneous tissue through interspinous plane was found. Conclusion Intramedullary abscess is a kind of rare disease,and is easily misdiagnosed. By analyzing the imaging and clinical informations carefully can improve the diagnostic rate.
