Abstract

The overall incidence of multiple meningiomas has been estimated to be about 8 percent since the introduction of the computerized tomography. The authors report a rare case of multiple meningioma that was composed of two histologically separate types occurring in intimate juxtaposition with each other and not intermixed. One of the multiple miningioma located in subtemporal region was meningotheliomatous type, whereas the other located in both the subtemporal and infratentorial region was psammomatous type. The clinical, radiological, and histopathological features of these lesions are discussed together with a review of the literature.
