There is no such thing as an arachnoid cyst that grows to a few years of age and then stops growing. Arachnoid cysts may grow all the time, but the growth rate cannot be judged due to large individual differences, which may be caused with primary arachnoid cysts, secondary arachnoid cysts, traumatic factors, and disease factors.
1. Primary arachnoid cysts: congenital arachnoid splitting abnormality, the cysts are not connected with the surrounding subarachnoid space, mostly seen in children.
2. Secondary arachnoid cysts: due to various reasons, the arachnoid membrane adheres to the surrounding soft membrane, and the cerebrospinal fluid forms a cystic cavity in the locally dilated subarachnoid space; the dirty layer of the cystic wall is the soft membrane, and the wall layer is the arachnoid membrane.
3. Trauma factors: when the patient’s head trauma, trauma to the spinal canal, etc. will trigger the disease.
4. Disease factors: if the patient suffers from brain tumor, intravertebral hemorrhage, spinal canal tumor and other diseases, it will increase the risk of the disease.
If the patient is not feeling well, he should go to the hospital in time and take targeted treatment under the doctor’s diagnosis.
