| glio- | Glue, gluelike (relating specifically to the neuroglia). Origin: G. Glia, glue (05 Mar 2000) |

| glioblast | An early neural cell developing, like the neuroblast, from the early ependymal cell of the neural tube; gives rise to neuroglial and ependymal cells, astrocytes, and oligodendrocytes. See: spongioblast. Origin: Glio-+ G. Blastos, germ (05 Mar 2000) |
| glioblastoma | <oncology, tumour> A malignant brain tumour that accounts for 75% of glial tumours (arising from glial cells in the brain). Treatment is difficult and consists of a combination of radiation therapy and surgery. (17 Dec 1997) |
| glioblastoma multiforme | <oncology, tumour> A malignant brain tumour that accounts for 75% of glial tumours (arising from glial cells in the brain). Treatment is difficult and consists of a combination of radiation therapy and surgery. (17 Dec 1997) |
| glioblastosis cerebri | A diffuse intracranial neoplasm of astrocytic origin. Synonym: astrocytosis cerebri, glioblastosis cerebri. (05 Mar 2000) |
| glioma | <oncology, tumour> Neuroectodermal tumour of neuroglial origin: include astrocytoma, oligodendroglioma and ependymoma derived from astrocytes, oligodendrocytes and ependymal cells respectively. All infiltrate the adjacent brain tissue, but they do not metastasise. (18 Nov 1997) |
| glioma of optic chiasm | A slow-growing tumour, usually an astrocytoma, of the optic chiasm in children. (05 Mar 2000) |
| glioma of the spinal cord | A glial tumour of the spinal cord, commonly an ependymoma; neoplasms of the spinal cord are relatively rare, but glioma's constitute approximately one-fourth of the total. (05 Mar 2000) |
| glioma, subependymal | An ependymoma in which there is a diffuse proliferation of subependymal fibrillary astrocytes among the ependymal tumour cells. Discrete lobulated ependymal nodules in the walls of the anterior third or posterior fourth ventricle are commonly found at autopsy. (12 Dec 1998) |
| gliomatosis | Neoplastic growth of neuroglial cells in the brain or spinal cord; the term is used especially with reference to a relatively large neoplasm or to multiple foci. Synonym: neurogliomatosis. (05 Mar 2000) |
| gliomatosis cerebri | A diffuse intracranial neoplasm of astrocytic origin. Synonym: astrocytosis cerebri, glioblastosis cerebri. (05 Mar 2000) |
| gliomatous | P ertaining to or characterised by a glioma. (05 Mar 2000) |
| gliomyxoma | <tumour> A myxoma that contains a considerable amount of proliferating glial cells and fibres. (05 Mar 2000) |
| glioneuroma | <tumour> A ganglioneuroma derived from neurons, with numerous glial cells and fibres in the matrix. (05 Mar 2000) |
| gliopil | <pathology> A matrix of glial cell processes composed mostly of astrocytes. (17 Dec 1997) |
