Primary intraventricular oligodendroglioma.

Oligodendroglioma, usually found in the cerebral hemispheres may invade the ventricles, however primary intraventricular oligodendroglioma is quite uncommon with only a limited number of cases reported in the literature. A 39-year-old woman harbouring a primary oligodendroglioma of the left lateral ventricle was treated by subtotal removal of the tumour through a left frontal transcortical transventricular approach. The clinical, radiological and surgical details of the case are presented in correlation with the current data on oligodendrogliomas. Benefits of postoperative irradiation are stressed.
