易误诊为椎管内肿瘤的腰椎间盘突出症分析

目的:探讨容易误诊为腰椎管内肿瘤的腰椎间盘突出症脱出型的原因。方法:回顾性分析6例该类型的腰椎间盘突出症的临床资料。结果:本组6例,都以腰椎管内占位收入院,全部经手术及术后病理证实为椎间盘突出。结论:容易误诊为腰椎管内肿瘤的腰椎间盘突出症,其特点是病史短,核磁影像显示:该类型腰椎间盘突出症椎管内占位(脱出的间盘)信号的高低和椎间盘信号相同,并且强化时不显影,同时需要发生在特定的腰椎节段。

Objective: To investigate the reason why prolapse of lumbar disc is easily misdiagnosed as lumbar intraspinal tumor. Methods: Clinical data of 6 cases of this type of lumbar disc herniation were retrospectively analyzed. Results: 6 patients in this group were all hospitalized for lumbar Intraspinal occupation lesion and were all confirmed as disc herniation after surgery and postoperative pathology.Conclusion:Lumbar disc herniation, often misdiagnosed as lumbar intraspinal tumor, is characterized by short term of disease history. MRI image shows that the signal level of the intraspinal space occupation(prolapsed disc) of this type of lumbar disc herniation is as same as that of the intervertebral disc and doesn’t develop image when intensified. The MRI image also shows that the prolapsed disc only occurs in a specific segment of lumbar vertebrae.
