Popular knowledge of intraspinal tumors Intraspinal tumors include various neoplastic lesions originating from different tissues in the spinal canal such as the spinal cord, nerve roots, spinal membrane or vertebrae. Intraspinal tumors can compress the spinal nerve roots and cause various neurological dysfunctions, which can seriously affect the quality of life of patients. What are the intradural tumors? Extramedullary tumors: neurofibroma and spinal meningioma are common in adults; intradural lipoma, epidermoid cyst, cyst of intestinal origin and teratoma are common in children. Intramedullary tumors: astrocytomas and ventricular meningiomas are common. Vertebral body tumors: including bone cysts and granulomas, chordoma and benign bone tumors What are the clinical manifestations of intradural tumors? Pain: It is often fixed in one place of the cervical, thoracic and lumbar back and radiates to the arms and thighs, with a nature like cutting and stabbing or burning, with intermittent episodes, aggravated or induced when coughing or sneezing hard. Sensory impairment: It is manifested by hypesthesia, numbness or ankylosis in the trunk or extremities. Motor disorders: cervical medullary lesions may have weakened muscle strength of the limbs; thoracolumbar lesions show weakness of the lower limbs and a feeling of stepping on cotton; sphincter dysfunction: patients have weakness in urination and defecation, urinary retention, urinary and fecal incontinence, and men may also develop impotence. How to treat intravertebral tumor? The main treatment method is surgical removal of tumor, which can be supplemented with radiation therapy for malignant tumors after surgery. Extramedullary intradural tumor is benign, once the diagnosis is clear, it should be surgically removed as early as possible, and it can mostly restore health. Intramedullary tumors are beneficial to complete resection of tumors with the help of microscope during surgery. For intramedullary malignant tumors, adequate decompression must be performed to relieve spinal cord compression symptoms in order to obtain longer-term symptom relief. Epidural malignant tumors can also be surgically resected and postoperatively supplemented with radiation therapy and chemotherapy. In recent years, we have performed laminar repositioning and spinal canal reconstruction techniques during surgery to preserve the anatomical integrity of the spine and avoid spinal deformities caused by spinal instability after laminectomy. For patients with spinal instability, vertebral body nail rod fixation is performed at the same time. What is the prognosis for intravertebral tumors? The prognosis of the tumor depends on the following factors: the nature and location of the tumor. The timing of treatment and the choice of approach. Early detection and treatment. The general condition of the patient. Surgical treatment can be considered as long as the patient can tolerate surgery. Strengthening postoperative care and functional exercise and preventing postoperative complications are very important for recovery.
