Intraspinal tumors are not as widely known as thyroid nodules and breast nodules, but if they are not detected and treated in time, they can cause serious harm. So, what are the typical symptoms of intravertebral canal tumor? 1.Pain Because of the limited location in the spinal canal, as the tumor grows, it will compress the spinal cord, nerves and blood vessels, resulting in a series of symptoms. One of the most common symptoms is pain, especially nerve root pain caused by nerve sheath tumor, which is most typical and spreads along the nerve root distribution area. The nerve root is mainly the connection site between the spinal cord and peripheral nerves, and the outgoing and incoming nerve impulses have to pass through the nerve root. Nerve root pain is mainly due to the occupancy of the tumor, which makes the sensory nerves constantly stimulated and thus sensory hypersensitivity occurs. This excessive nerve impulse then brings a tingling sensation to the body, and the pain is produced along the distribution area of the nerve root. Generally speaking, if the tumor outside the spinal cord directly presses the nerve root or the surrounding nerves, the nerve root pain is more likely to appear; if the tumor grows in the spinal cord, the symptoms of nerve root pain are not obvious in contrast. Not only that, some patients may also feel soreness or burning pain, and may also have various sensory abnormalities, such as numbness, as if there are ants crawling in the back, the feeling of being bound in the back, the coolness of the back, and so on. Some patients may not even feel pain or temperature, or their sense of touch may be diminished or even absent. However, there are questions raised, these symptoms are actually quite similar to lumbar spondylosis, how to distinguish? In fact, one typical manifestation of lumbar spondylosis is intermittent claudication, which means that the pain will be aggravated when the patient stands too long or walks too much, and will be relieved by lying down and resting. For the pain caused by intravertebral tumor, it is often obvious when resting at rest, but relieved after activity. However, it is difficult to determine what the disease is through these symptoms alone, and often requires professional examination by clinicians as well as imaging examinations. 2.Compression symptoms Some congenital intravertebral tumors compress the nerves and also lead to urinary and fecal dysfunction, such as constipation, frequent urination, urinary weakness, urinary retention, etc.; or manifestations of movement disorders, such as limb stiffness, weakness, limited mobility, muscle atrophy and muscle bundle tremors, etc., or even deformities of both lower limbs as the individual grows and develops. 3.Spinal deformity Although intravertebral tumor and spinal tumor grow in different locations, don’t think that intravertebral tumor will not cause spinal deformity. Some malignant tumors in the spinal canal grow very fast and can protrude from the spinal canal and accumulate the spine. If it is severe enough to involve the articular eminence it can easily cause spinal deformity, but this is relatively rare. It is often when the tumor is large enough to destabilize the spine that it can cause spinal deformity. Generally speaking, it is very rare for intravertebral canal tumors to cause spinal deformity. However, some children with congenital intravertebral canal tumors not only have tumors in the vertebral canal during growth and development, but also have developmental deformities of the spine, which is a case of co-existence of tumors and spinal deformities. 4.Spinal cord embolism It is worth noting that tumors in the spinal canal can also lead to spinal cord embolism, especially congenital tumors, which are gradually formed during embryonic growth and development. As the spinal column develops, the spinal canal tumor near the lumbosacral spine will pull on the cauda equina at the lower end of the spinal cord, causing embolism. This is a secondary embolism, which is different from the primary spinal cord embolism. In the case of primary spinal cord embolism, the child will gradually develop urinary and fecal disorders and abnormal development of both lower extremities after birth, independent of the size of the tumor, as the child grows and develops. In the case of secondary spinal cord embolism caused by intravertebral tumors, the symptoms tend to appear later, usually when the tumor grows large enough to pull on the spinal cord.
