    A glimmer ot hope was aroused hv the efforts of Jumentie, of Challiol and of Jacarelli to find a clinical syndrome by which tumors iu the lateral ventricle could be localized, but this hope was quickly doomed to disappointment. After reviewing all available cases, including their own after the necropsy findings had been disclosed, they were forced to conclude that a clinical entity does not exist. Jacarelli, however, thought it possible that ventriculography might be helpful. From tin* series of fifteen cases which form the basis of this communication and from which the neurological signs and symptoms have been analyzed, the writer is also forced to conclude that neither objective findings nor subjective symp¬ toms can lead to the diagnosis of tumors iu tin' lateral ventricle. There are, as will be shown, reasons for suspecting such tumors, but to explore a lateral ventricle through a deep cortical in¬ cision only on suspicion is indefensible. Ventriculography has entirely transformed this picture. By this method the diagnosis and localization of all ventricular tumors causing pressure can be made with such accuracy that they may, without exception, be disclosed at operation. Moreover, this precision in diagnosis is not only easy and certain, but is attainable without risk to life or function. And although the operative removal of such deeply situated tumors is necessarily serious, increasing experience has already greatly reduced tin* risk to life and function. It will also be seen that primary benign tumors in the lateral ventricles are much more common than the reports-from the literature would lead us to believe. They represent perhaps 1 per cent of all brain tumors- a frequency slightly less than encapsulated tumors in the third ventricle. The first primary benign tumor iu the lateral ventricle to be found at operation and completely removed was reported by the writer in 1!)L2<) (Case 1 of this series). The localization was made by ventriculography (11)1 S) after two attempts to find the tumor had been unsuccessful. This happened to be the first brain tumor to be localized by this method.
