Glioma
Definitions related to ganglioglioma:
-
A well differentiated, slow growing neuroepithelial neoplasm composed of neoplastic, mature ganglion cells and neoplastic glial cells. Some gangliogliomas show anaplastic features in their glial component and are considered to be WHO grade III. Rare cases of newly diagnosed gangliogliomas with grade IV (glioblastoma) changes in the glial component have also been reported. (Adapted from WHO)NCI ThesaurusU.S. National Cancer Institute, 2021
-
Ganglioglioma is a rare, usually benign, well-circumscribed, often cystic, mixed neuronal-glial tumor (composed of both neoplastic glial and ganglionic elements) which is typically located in the temporal lobe and rarely invades the surrounding tissue. Patients usually present with seizures refractory to medical treatment. Association with neurofibromatosis type I and tuberous sclerosis has been reported.OrphaNetINSERM, 2021
-
Gangliogliomas are rare tumours of the central nervous system. The are WHO grade I and considered low grade. They are well differentiated neuroepithelial tumours consisting of both dysplastic neuronal and neoplastic glial cells.Human Phenotype Ontology (HPO)The Human Phenotype Ontology Project, 2021
-
Rare indolent tumors comprised of neoplastic glial and neuronal cells which occur primarily in children and young adults. Benign lesions tend to be associated with long survival unless the tumor degenerates into a histologically malignant form. They tend to occur in the optic nerve and white matter of the brain and spinal cord.NLM Medical Subject HeadingsU.S. National Library of Medicine, 2021
-
A ganglioglioma is a rare type of brain tumor, accounting for approximately 1% of all brain tumors. Gangliogliomas occur when a single cell in the brain starts to divide into more cells, forming a tumor. This can occur when the cell randomly acquires changes (mutations) in genes that regulate how a cell divides. Most gangliogliomas grow...National Center for Advancing Translational Sciences
