Glioma

Is a type of tumour that starts in the brain or spine. It is called a glioma because it arises from glial cells.

Any tumour of the glial tissue in the brain or spinal cord.

General term for a tumor arising from within the brain, generally malignant.

Tumor of glial cells graded by degree of invasion.

A brain tumor arising from the glial cells, which form the supporting tissues of the central nervous system. Gliomas are known by the names of the several cell types from which they develop. Like other brain tumors, gliomas can lead quickly to an increase in pressure inside the skull. Symptoms resulting from the pressure and the tumor can vary greatly, depending on the location and size of the growth. They may or may not include headache, vomiting, double vision, partial paralysis, loss of sensation, seizures, and personality changes.

Any tumor of non-nervous cells (glia) in the nervous system. The term is sometimes used for all tumors that arise in the central nervous system, including astrocytomas, oligodendrogliomas, ‘medulloblastomas, and ependymomas. Tumors of low-grade malignancy produce symptoms by pressure on surrounding structures; those of high-grade malignancy may be invasive.

A tumour in the brain or spinal cord, composed of neuroglia, which is the special connective tissue that supports the nerve cells and nerve fibres. Low-grade malignant gliomas cause symptoms by putting pressure on surrounding tissues and organs. Highly malignant gliomas are usually invasive. Gliomas, like other space-occupying tumours in the brain, may present with headaches, seizures, neurological symptoms or symptoms of mental disturbance. Treatment may include surgery, radiotherapy and chemotherapy and should be done in a specialist neurological center.

A glioma is a kind of brain tumor that originates from the connective tissue, known as glial cells, in the brain. Varieties of glioma include astrocytoma, glioblastoma multiforme, ependymoma, medulloblastoma, and oligodendroglioma. The symptoms, diagnosis, and treatment are similar to those for other kinds of brain tumors.
