NCI: A rare, slow-growing tumor that begins in the oligodendrocytes (brain cells that provide support and nourishment for nerve cells).,NCI: A neoplasm of the central nervous system composed predominantly of cells morphologically resembling oligodendroglia. Oligodendroglial tumors histologically comprise a continuous spectrum ranging from well-differentiated neoplasms to frankly malignant tumors. WHO grading system recognizes two malignancy grades: WHO grade II for well-differentiated tumors (oligodendroglioma) and WHO grade III for anaplastic oligodendroglioma. (Adapted from WHO)
