title: [Multiple meningiomas. Part I. Types. Classification. Differential Diagnosis].
abstract: Meningiomas usually are solitary tumors but they can be multiple in various conditions. True multiple meningiomas in the sense of Cushing are rare. The development of more than one meningioma in the same individual may be due to central neurofibromatosis or following external cranial irradiation. Multiple meningiomas can occur after dissemination of the tumor cells following surgery. The purpose of this review is to define and discuss the different types and the criteria of differential diagnosis for MM.
