ABSTRACT
Introduction: Intraspinal tumors were primary and secondarytumors that occurred in the spinal cord, nerve roots, meningesand the tissue of the wall of vertebral canal. Study aimedto analyze the misdiagnosis causes of intraspinal tumorsmisdiagnosed as lumbar intervertebral disc herniation, and toreduce the rate of clinical misdiagnosis.Material and Methods: Clinical data of 19 patients withintraspinal tumors misdiagnosed as lumbar intervertebral discherniation were retrospectively analyzed, and the respectivecharacteristics, essentials for diagnosis and differentialdiagnosis of the two different kinds of diseases weresummarized. The misdiagnosis causes were analyzed, and theprevention measures were put forward.Results: All the misdiagnosed patients’ data on MRI werecollected, and then they received operative treatment.Histological diagnosis results showed that there were 13cases of schwannomas, 3 cases of meningiomas, 2 casesof ependymomas, and 1 case of angiomyolipoma. In 1~36months’ follow-up, pain of all the patients was alleviated.Eighteen patients were healed, and only one patient still feltnumbness at left hip and left leg. No patient reoccurred ordied.Conclusion: Though there were similarities in early clinicalmanifestations between intraspinal tumors and lumbarintervertebral disc herniation, these two different kinds ofdiseases can be identified by collecting the case historydetailedly, performing physical examination carefully, andchoosing the imaging examination appropriately to avoidmisdiagnosis.
