Motor conduction tract involvement is one of the clinical manifestations caused by primary intraspinal tumors. When the cervical spinal cord is partially compressed, with the increase of tumor, the symptoms of spinal cord conduction bundle compression will gradually appear on the basis of the original symptoms, such as compression of spinal cord thalamus bundle, which may lead to hyperalgesia or disappearance of pain and temperature sensation below the contralateral side of the lesioned segment; compression of posterior bundle, which may lead to hyperalgesia of deep sensation; involvement of motor conduction bundle, which may lead to upper motor neuron paralysis in the limbs below the ipsilateral lesioned segment, and spinal cord hemisection syndrome is a specific symptom of intradural extramedullary tumor. The spinal cord hemisection syndrome is a specific symptom of extramedullary tumor. The differential diagnosis of motor conduction tract involvement: The clinical manifestations of intravertebral tumors are diverse and often misdiagnosed if care is not taken, resulting in varying degrees of paralysis before the diagnosis is confirmed. The clinical manifestations of cervical intradural tumors are very similar to those of cervical spondylosis, and because of the high incidence of degenerative spinal disease, spinal cord tumors are often overlooked, causing patients to experience longer periods of ineffective treatment and increasing the risk of irreversible damage to spinal nerves. In this regard, clinicians should pay great attention to it. Ni Bin et al. reported 137 cases of early cervical intradural tumors misdiagnosed as cervical spondylosis in 21 cases, among which 2 cases were mistakenly treated with cervical decompression surgery. The most important reason for misdiagnosis is the lack of awareness and vigilance of intravertebral canal tumors. Neglect of medical history and basic examination is also an important reason. Patients with mild symptoms or spontaneous remission can be treated conservatively with repeated, multiple physical examinations and MRI reviews (note: risk of recurrence and bleeding from spinal cord injury). However, the only effective treatment is surgical resection of the tumor. Since primary intravertebral tumors are mostly benign, about 3/4 of cases can be cured by surgical resection, therefore, surgical resection of intravertebral tumors should be strived for, even if they cannot be completely removed, partial or large resection should be performed to reduce or relieve the compression and damage of the tumor on the spinal cord. Once the diagnosis is clear, surgical conditions should be created actively, and regardless of the degree of spinal cord compression, surgery should be performed in time. Surgery has risks, and the risk of repeated surgery varies depending on the functional location of the tumor, with few postoperative defects in exogenous cases. The appropriate treatment should be selected. Intraoperative spinal cord evoked potential monitoring helps to reduce neurological complications. If the intravertebral tumor can be detected early and treated with surgery early, most of them achieve good clinical results. Some patients with large intradural tumors or located in high cervical spine may die after surgery due to respiratory failure or recur some time after surgery. As for the recovery of spinal nerve function, it is related to the degree and time of spinal cord compression of patients.
