ol·i·go·den·dro·gli·o·ma ( l  -g -d ndr-gl - m , -gl -)n. A relatively rare and slow-growing glioma characterized by numerous small, round or ovoid oligodendroglial cells uniformly distributed in a sparse fibrillary stroma. |
oligodendroglioma
[ol′igōden′drōglī·ō′mə] pl. oligodendrogliomas, oligodendrogliomata
Etymology: Gk, oligos + dendron, tree, glia, glue, oma, tumor
an uncommon brain tumor composed of nonneural ectodermal cells that form part of the supporting connective tissue around nerve cells. The lesion, a firm reddish-gray mass with calcified spots and a distinct margin, may be large. The tumor develops most often in frontal, parietal, and paraventricular sites but also may occur in the cerebellum. Also called oligodendroblastoma.
oligodendroglioma, (ol´igōden´drōglēō´m
),n a relatively rare, moderately well-differentiated, relatively slow-growing glioma that occurs most frequently in the cerebrum of adults. It is grossly homogeneous, fairly well-circumscribed, moderately firm, and somewhat gritty in consistency, with interstitial calcification sufficiently dense to allow detection by radiographic imaging of the skull.
