ependymal tumor | definition: glioma arising in the ependyma, i.e. the cellular membrane lining both the central canal of the spinal cord and the spaces in the brain where special fluid that protects the brain and spinal cord or cerebrospinal fluid is produced and stored (brain ventricles). Its cells are relatively undifferentiated and are attached to blood vessels. Ependymal tumors are classified according to the histologic grade of the cells in the tumor (how different the tumor cells are from the cells that are near it) into well-differentiated ependymoma, anaplastic ependymoma and ependymoblastoma. Ependymal tumors are most common in children and young adults. (en) number: singular part of speech: noun reliability code: 10 term type: main entry term |

tumor ependimal | definition: cáncer que se origina en el epéndimo (membrana celular que tapiza el conducto central de la médula espinal y los ventrículos cerebrales, es decir, las cavidades del cerebro donde se produce y almacena el fluido cerebrospinal, que protege el cerebro y la columna vertebral). Sus células están relativamente indiferenciadas y están adheridas a los vasos sanguíneos. Estos tumores se clasifican según el grado de diferenciación histológica en ependimomas bien diferenciados, anaplásicos y ependimoblastomas. Los tumores ependimales suelen afectar a niños y adolescentes. (es) gender: masculine number: singular part of speech: noun reliability code: 10 term type: main entry term |
