Objective       To analyze the misdiagnosis causes of intraspinal tumors misdiagnosed as lumbar intervertebral disc herniation

and reduce the clinical rate of misdiagnosis.         Methods       Clinical data of 19 patients with intraspinal tumors misdiagnosed as lumbar intervertebral disc herniation were retrospectively analyzed

and the respective characteristics

essentials for diagnosis and differential diagnosis of the 2 kinds of diseases were summarized. The misdiagnosis causes were analyzed

and prevention measures were put forward.         Results       All the misdiagnosed patients performed MRI scanning

and then received operative treatment. Histological diagnosis results showed that there were 13 cases of schwannomas

3 cases of meningiomas

2 cases of ependymomas

and 1 case of angiomyolipoma. In 1~36 months’ follow-up

pain of all the patients was alleviated. Eighteen patients were healed

and only one patient still had numbness at left hip and left leg. No patient reoccurred or died.         Conclusion       Though there are similarities in early clinical manifestations between intraspinal tumors and lumbar intervertebral disc herniation

the two kinds of diseases can be identified to avoid misdiagnosis through collecting the detailed history

performing careful physical examination

and choosing the appropriate imaging examination.
