Transparent septal cyst is not a tumor or a vascular disease, it is actually some water, but this water is not enough to cause obvious clinical symptoms, and many people have this condition, so there is no need to worry about special factors: 1, it may be a congenital developmental abnormality, because this part of the nerve cells may not be completely separated in the process of development, or produce certain adhesions, thus causing a transparent septal cyst. 2. previous intracranial inflammatory reactions or traumatic reactions, resulting in certain soft tissue adhesions, which may also form hyaline septal cysts. This is not a concern, and generally does not require treatment or oral medication when it does not cause obvious clinical symptoms. If a septal cyst does produce significant clinical symptoms, it can be removed surgically, but this is not usually necessary and may occur in very few people.
