Abstract

Oligodendroglioma represents the second major category of diffuse gliomas, accounting for 3–4% of all primary brain tumors. There are two WHO grades of oligodendroglioma that are significant predictors of survival: grade II or well-differentiated tumors and grade III or anaplastic oligodendroglioma. Frozen sections of oligodendrogliomas almost invariably produce misleading cytoplasmic and nuclear artifacts, which is why the cytologic technique is preferable for intraoperative consultation. This chapter reviews the cytomorphologic features and intraoperative differential diagnosis of oligodendroglioma and anaplastic oligodendroglioma.
