The distribution of intraspinal tumors in children is different from that of adults, 40% of which are located in the spinal cord, while in adults this proportion is only 20%, common astrocytic tumors and embryonic tumors such as teratomas, epidermoid cysts, dermatoid cysts, intestinal cysts, etc.; subdural extramedullary tumors accounted for 10%, compared to 60% in adults, common nerve tumors and spinal tumors. Epidural tumors accounted for 50%, and 20% in adults, mostly malignant tumors, common neuroblastoma, ganglioneuroblastoma, various types of sarcoma (such as Ewing’s sarcoma, osteosarcoma, rhabdomyosarcoma and neurofibrosarcoma, etc.), benign tumors are also the most common in the nerve tumor. Intravertebral intestinal cysts Intravertebral neuroblastoma What are the special clinical manifestations of intravertebral tumors in children Children, especially young children, do not yet have the ability to communicate verbally and are unable to express themselves exactly, so it is not easy for doctors to grasp their symptoms when they visit the doctor. Therefore, it is not easy for doctors to grasp their symptoms when they visit the doctor. It is more important for healthcare professionals to take medical history, conduct physical examination and auxiliary examination carefully. In general, the most common manifestations of intravertebral tumors in children are pain, limb weakness, and dysfunction of urination and defecation, while the other symptoms, in order of frequency, are altered sensation, curvature of the spine, and detection of a mass. Physical examination sometimes reveals spastic strabismus. A few tumors, especially intramedullary tumors of the cervical medulla in children, may occasionally cause hydrocephalus. It is currently believed that the causes may be as follows: tumors may cause increased protein levels in the cerebrospinal fluid (CSF), resulting in slower absorption of CSF; tumor implantation may block the circulatory pathway of the CSF; and subarachnoid hemorrhage caused by bleeding of the tumor may affect the absorption of the cerebrospinal fluid. There are also some congenital tumors in children, often combined with the existence of congenital malformations of the spinal cord and spine, such as occult spina bifida, hidden hairy sinus and other malformations, etc., which need to cause great attention of parents and doctors. What are the special features of the treatment of intraspinal tumors in children? The aim of treatment for intravertebral tumors in children is to define the pathological nature of the tumor, resect the lesion, relieve or eliminate the compression of the neural structures as well as rebuild or maintain the stability of the spine. The choice of tumor resection method, as well as the implementation or non-implementation of radiotherapy, is the same as that of general intradural tumors, but postoperative spinal stability is a more prominent issue in pediatric patients. Some experts believe that the use of laminectomy to reveal and remove the tumor is more conducive to maintaining spinal stability after surgery; for children undergoing laminectomy, X-ray films should be taken every 3 months in the first year after surgery to find out whether there is a “gooseneck-like” deformity or other spinal deformities, so as to take timely measures to cope with the situation. In addition, non-surgical treatments such as asymmetric radiation therapy can also cause abnormal spinal curvature, which also requires attention. Therefore, some experts currently believe that the combination of surgical treatment and radiation therapy should be avoided as much as possible.
