Abstract

Eight cases with coexistence of a brain tumor and cerebral aneurysms were found through the review of the authors' series of 198 brain tumors over a period of eight years. They were treated successfully with no operative mortality. Histological diagnoses of these eight tumors were meningiomas in four, pituitary adenomas in two, a glioblastoma multiforme and an acoustic neurinoma. Clinical significance of the coexistence was discussed with special stress on etiology. It can be incidental in many cases. However, in three out of eight cases, hemodynamic change due to peripherally located tumors was suspected as a cause of aneurysm development in their proxymal arteries.
