摘　　要：目的:对颈段脊髓髓内室管膜瘤使用核磁共振检测的鉴别诊断价值进行分析,为提高检测效率提供参考。方法:收集具备颈段脊髓髓内室管膜瘤基本核磁共振检查表现的病例及其相关资料进行分析。结果:研究样本105例,3位放射科医生共给出315例诊断结果,315例中将患者诊断为颈段脊髓髓内室管膜瘤的患者有205例,剩余患者中确诊为脊髓蛛网膜炎的34例、椎间盘突出的29例、硬脊膜外脓肿的33例、星形细胞瘤的14例,医生阅片结果与金标准结果差异有统计学意义;影响放射科医生阅片结果的相关因素包括患者年龄、是否新发、是否合并高血压、脑脊液细胞数、上下肢运动功能以及躯体各项感觉水平(均有P<0.05)。结论:核磁共振检测对颈段脊髓髓内室管膜瘤的诊断价值总体较优,但误诊和漏诊的现象仍然存在。Objective:To analyze the differential diagnosis value of cervical spinal cord intramedullary ependymoma using MRI to provide reference for improving the detection efficiency.Methods:The cases with basic MRI findings of cervical spinal cord intramedullary ependymoma and their related data were collected and analyzed.Results:Among the 105 cases in the study sample,3 radiologists gave a total of 315 diagnostic results.Among the 315 cases,205 cases were diagnosed as cervical spinal cord intramedullary ependymoma,and the remaining patients were diagnosed as spinal cord arachnoid.There were 34 cases of inflammation,29 cases of intervertebral disc herniation,33 cases of epidural abscess,and 14 cases of astrocytoma.The difference between the results of doctor reading and the gold standard was statistically significant;The related factors affecting the results of radiologists'reading include patient age,new-onset,hypertension,cerebrospinal fluid cell count,motor function of upper and lower extremities,and various somatosensory levels(all P<0.05).Conclusion:The diagnostic value of MRI for intramedullary ependymoma of the cervical spinal cord is generally better,but misdiagnosis and missed diagnosis still exist.
