People’s first reaction to frequent back pain is probably more spinal disorders, such as lumbar disc herniation and lumbar prolapse. In fact, the spinal canal and spinal cord are also structures that are closely related to the spine. If a tumor grows in the spinal canal or even the spinal cord and invades the blood vessels and nerves, it can be equally painful. As we all know, the spine is one of the most important structures that support the human form. The spine is mainly composed of one vertebrae, and the vertebral holes in the middle of the upper and lower vertebrae are connected, forming a tubular structure – the spinal canal. The spinal canal is lined with layers of membranous structures and infiltrated with cerebrospinal fluid, which together encase the spinal cord in the middle and protect it. So-called intravertebral canal tumors are tumors that grow on these tissue structures within the spinal canal. One type of intravertebral tumor is congenital and occurs mostly in infants and young children. When developmental abnormalities occur during the embryonic growth and development, intravertebral tumors are likely to form. The other type may be caused by environmental pollution, radiation and other factors, mostly seen in adults. Or intravertebral canal malignant tumors formed by metastasis of cancer cells from other sites. However, intravertebral canal tumors are often easily considered to be spinal tumors because it is difficult to distinguish the two from each other in terms of symptoms. However, there is a clear difference in the growth location of these two types of tumors, spinal tumors are tumors growing in the spine or intervertebral discs, which affect the normal structure and function of the spine, and usually have to be seen in orthopedics or spine surgery. A few intracanal tumors may pass through the intervertebral space and protrude outside the spinal canal and invade the spine, but this is different from tumors growing directly on the spine or destroying the spine, and the degree of damage to the bone is different. Intraspinal tumors often require a trip to neurosurgery, where the surgeon can deal with the neurological and vascular aspects. Although it is difficult to distinguish between symptoms caused by spinal tumors and intradural tumors, there is a difference in how early the symptoms appear. Intradural tumors tend to present early with painful symptoms, while spinal tumors are more commonly associated with impaired motion and painful sensations appear later.
