TUMORS OF THE BASAL GANGLIA

Abstract

The purpose of this work was to investigate whether an analysis of the extrapyramidal syndromes as reported by various authors, particularly by Wilson,¹Foerster,²von Monakow³and others, would be of any assistance in the diagnosis of a tumor arising in or invading the basal ganglia. In order to make the study as nearly exact as possible, only those cases in the entire series have been selected in which the definite localization of the tumor has been verified by postmortem examination, the exact topography of a lesion often remaining obscure from the operative point of view alone. Since no particular histologic type of tumor originates specifically from the basal ganglia, it has been necessary to include as tumors of the basal ganglia not only the primary growths arising in them, but also the secondary ones which indirectly affected and destroyed this part of the brain. Though the
