BACKGROUND: 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.
CASE REPORT: We describe a rare case of simultaneous occurrence of two skull base meningiomas in a 66-year-old female. This patient underwent low-dose irradiation for tinea capitis when she was 8 years old. The patient complained of nuchal pain, paresthesias in both hands, and progressive weakness on her right side. She was admitted to the hospital in September 1994. An MRI showed two masses, one located at the level of the tuberculum sellae and the other at the foramen magnum. These seemed very likely to be multiple meningiomas. The latter lesion, which was more symptomatic and dangerous, was operated on first. Six months later, elective treatment of the suprasellar meningioma was performed with success.
CONCLUSION: 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.
