Preferred Label : oligodendroglioma;
RADLEX synonyms : oligodendroglioma (WHO grade II);
Definition : A relatively slow-growing glioma that is derived from oligodendrocytes and tends to
occur in the cerebral hemispheres, thalamus, or lateral ventricle. They may present
at any age, but are most frequent in the third to fifth decades, with an earlier incidence
peak in the first decade. Histologically, these tumors are encapsulated, relatively
avascular, and tend to form cysts and microcalcifications. Neoplastic cells tend to
have small round nuclei surrounded by unstained nuclei. The tumors may vary from well-differentiated
to highly anaplastic forms. (From DeVita et al., Cancer: Principles and Practice of
Oncology, 5th ed, p2052; Adams et al., Principles of Neurology, 6th ed, p655) [MeSH];
