BACKGROUND: The incidence of @entity1297 varies from 1 to 3% in different series. Skull base @entity1653 are rare. The pathogenetic role of low-dose radiation seems to be fairly well established in the oncogenesis of @entity1653 . Calvarial location and multiplicity seem to be among the distinctive features of radiation-induced @entity1653 . 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 @entity1653 in a 66-year-old female. This @entity1 underwent low-dose irradiation for @entity3100 when she was 8 years old. The @entity1 complained of @entity158 , @entity809 in both hands, and progressive @entity425 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 @entity1653 . The latter lesion, which was more symptomatic and dangerous, was operated on first. Six months later, elective treatment of the @entity1804 was performed with success. CONCLUSION: The actual role of previous head irradiation in the oncogenesis of the @entity1653 remains somewhat unclear. Proper management and judicious use of skull base surgery techniques were key factors in the successful treatment of the @entity1 .
