An ependymoma is a primary central nervous system (CNS) tumor. This means it begins in the brain or spinal cord. To get an accurate diagnosis, a piece of tumor tissue will be removed during surgery, if possible. A neuropathologist should then review the tumor tissue.
17 sie 2024 · Ependymomas represent a relatively broad group of glial tumors with ependymal differentiation. They often arise from or near the lining of the ventricles of the brain or the central canal of the spinal cord but also occur within the brain parenchyma.
An ependymoma is a tumor that arises from the ependyma, a tissue of the central nervous system. Usually, in pediatric cases the location is intracranial, while in adults it is spinal. The common location of intracranial ependymomas is the floor of the fourth ventricle. Rarely, ependymomas can occur in the pelvic cavity.
21 kwi 2023 · Learn about this tumor that forms from ependymal cells in the brain and spinal cord. Treatments include surgery, radiation therapy and chemotherapy.
16 paź 2019 · Ependymomas are glial cell tumors that commonly arise in the lining cells of the ventricular system, and less commonly outside the central nervous system (CNS), or within the brain parenchyma. They are comprised of genetically distinct subgroups of tumors and affect children more commonly than adults. [1]
6 kwi 2022 · Ependymomas are neuroepithelial tumors that may arise from the ependymal cells of the cerebral ventricles, the central canal of the spinal cord, or cortical rests. According to the Central Brain Tumor Registry of the USA, the annual incidence of ependymomas ranges from 0.29 to 0.6 per 100,000 persons [ 1 ].
21 mar 2022 · Newly identified biological markers and classification schemes, e. g. based on global DNA methylation profiling, have led to the definition of 10 types of ependymal tumors and an improved prediction of patients’ outcome by applying the new classification system.
