The incidence of multiple skull base meningiomas varies from 1 to 3% in different series. Skull base meningiomas are rare. The pathogenetic role of low-dose radiation seems to be fairly well established in the oncogenesis of meningiomas. Calvarial location and multiplicity seem to be among the distinctive features of radiation-induced meningiomas. Skull base location is a very rare occurrence, mainly because the path of irradiation does not significantly involve this region. ⋯ The actual role of previous head irradiation in the oncogenesis of the present meningiomas remains somewhat unclear. Proper management and judicious use of skull base surgery techniques were key factors in the successful treatment of the patient.
