Abstract

Oligodendrogliomas as a distinct group were first described by Bailey and Cushing,1 and an accurate description of the histologic features of the tumor has been given by Bailey and Bucy,2 Környey3 and other authors. Little attention, however, has been paid to the gross pathologic character of this complicated neoplasm, except in the intraventricular type, which was studied by Bailey and Cushing,1 Dickson,4 Greenfield and Robertson,5 Kwan and Alpers6 and Thomas and Jumentié.7 It is the purpose of this paper to demonstrate that this tumor may be classified under several varieties as determined by its distribution and type of growth. From our material the following classification may be made: (1) bilateral type, involving both hemispheres; (2) unilateral type, involving one hemisphere; (3) oligodendroglioma of the ventricles and (4) oligodendroglioma of the basal ganglia. In the literature we have found additional types, with involvement
