Spinal nerve sheath tumor is a common tumor that occurs in the spinal canal, also known as vertebral canal Chewang’s cell tumor, and accounts for about 25% of spinal canal tumors. The vast majority of spinal nerve sheath tumors are benign and slow-growing, with only a very small percentage of nerve sheath tumors, about 2.5%, being malignant. Because tumors grow slowly and produce symptoms that are easily tolerated by patients, many patients have already grown very large by the time they are seen, delaying treatment. Therefore, it is important to consider the possibility of a spinal nerve sheath tumor when you notice persistent, inexplicable pain and numbness in a certain area of the body. Sometimes the tumor growth will continue to grow along the interspinal space such as the intervertebral foramen or subdural space, and in some cases the tumor can protrude into the subcutaneous cervical area, the thoracic cavity, or even the abdominal cavity. They can occur in all segments of the spinal canal and are mostly solitary, with a peak incidence between the ages of 40 and 60, with no significant difference between the sexes. Some nerve sheath tumors may cause acute spinal cord neurological dysfunction due to cystic degeneration or hemorrhage, such as sudden onset of limb pain, limb paralysis, urinary and fecal disorders, etc. In this case, it is important to seek immediate medical attention and surgical treatment as soon as possible.
