title: Oligodendroglioma with a twenty-two year history. Clinicopathological case report.
abstract: Clinico-pathologic report of a patient with an oligodendroglioma who ran a 22-year course characterized by focal epileptic seizures of the Jaksonian type. The EEG remained normal for many years. Since the tumor had not been influenced by therapeutic measures, the histologic picture permitted considering some basic problems of origin, growth, and differentiation of oligodendrogliomas.
