A case of multifocal oligodendroglioma was described in a 51-year-old woman. Tumours were located in the parietal lobe of the right cerebral hemisphere and in the frontal lobe of the left cerebral hemisphere. Multifocal character and type of the neoplasm were determined by using computerized+ tomography and fine-needle biopsy with the patient alive. Histologic examinations of the surgical and autopsy materials confirmed multifocal development of oligodendroglioma.
