Objective : Intra or periventricular tumors of the central nervous system such as
oligodendroglioma and central neurocytoma, are frequently associated with hydrocephalus
and histologically scare the presence of relatively uniform, small round nuclei and
perinuclear halos. The two entities may be difficult to discriminate from one another
from surgical specimens by a routine histologic examination.
The aim of this study is to characterize anti distinguish better of these two entities
by examining tissue cultural characteristics.
Materials and Methods : Total of 12 oligodendrogliomas and central neurocytomas
were studied. Sterile fresh tumor tissues were mechanically and enzymatically
dissociated into individual cells, and seeded onto 6 well culture dish with poly-L-lysine
precoated Aclar coverslips placed in a well.
The oligodendroglioma cells attached to the surface of the coverslips after 4 to 5
days, and easily detached by a mechanical shaking. The growth cycle of the
oligodendroglioma cells show longer lag please and shorter log phase than central
neurocytoma cells. The central neurocytoma cells attached it within 12 to 24 hours, and
thin, delicate cytoplasmic processes developed by 2 to 3 days after the preparation.
Immunohistochemical stains for galactocerebroside and GFAP were positive in the
cultured tumor cells of oligodendroglioma, and MAP2 and synaptophysin(SYP) in central
neurocytoma, respectively.
Conclusion : The cultural characteristics can be used as a simple and reliable method
for a differential diagnosis of oligodendroglioma and central neurocytoma located in the
ventricular region of the brain.
