Oligodendrogliomas

Abstract

Oligodendrogliomas are tumours developed from oligodendrocytes. They may be pure or associated with astrocyte proliferation. They are usually benign, but their malignancy grade is varied. These tumours affect middle-aged adults and are characterized by their slow growth and their fairly suggestive neuroradiological features which are those of a large, calcified, poorly enhanced, peripheral frontal lesion. Computerized tomography and magnetic resonance imaging are suitable complementary methods to characterize the tumour and evaluate its extension.
