More consideration is being given to the subject of tumors of the brain now than at any time in the history of medicine and surgery. Reasonably early diagnosis and localization of these lesions in the recent past have been impossible in most cases, and less than 10 per cent of patients with tumors of the brain have recovered. The so-called silent areas of the brain are still extensive, and there is much confusion in dealing with the various causes of chronic headache and pain in the head. However, improved methods of diagnosis and a better general understanding of tumors of the brain lend encouragement to an altogether better outlook.
At the present time, correct diagnosis and localization can be made in about 90 per cent of all tumors of the brain, but in the majority of cases the information is obtained too late to be of material benefit to
