Subarachnoid Hemorrhage Consequent to Intracranial Tumors

Not infrequently one hears discussed the possibility of subarachnoid hemorrhage occurring as an initial manifestation of intracranial tumor. Owing to the fact that spontaneous subarachnoid hemorrhage is most generally associated with intracranial aneurysms, this possibility (hemorrhage with brain tumor) too often is considered lightly and dismissed at the bedside. Because we had clinically encountered this condition more commonly than expected, we felt that the problem deserved further consideration; therefore, we undertook a survey of our cases and of the literature in order to define more accurately and clearly the clinical and pathological aspects of subarachnoid hemorrhage consequent to intracranial tumors. It was hoped that from this study we might better approach the problems of diagnosis and therapy in the presence of acute subarachnoid hemorrhage. The medical literature on subarachnoid hemorrhage and brain tumors is extremely voluminous, and it has been impossible to review every paper. However, we have endeavored to
