A glioma is a tumor
in the nervous system from the glial tissue, meaning the supportive tissue of the neurons
. Gliomas can be benign
, with different types designated by the names astrocytoma
, ependymoma, and oligodendroglioma, or malignant
in which case they are called glioblastoma
. They occur primarily due to an intracranial pressure, a side-effect
of the increased pressure generated in the inextensible skull involving headaches
, vomiting, and eye disorders. Other symptoms are possible and depend on the location of the tumor and areas that are compressed by hypertension
. A CT scan or MRI
can detect the tumor. The treatment of glioma is mainly surgical: the tumor is removed; it may be accompanied by chemotherapy
or radiotherapy if the tumor is cancerous.
