title: Primary meningioma intimately related to skull: case report and review of the literature.
abstract: A report is made of a primary meningioma intimately associated with the left sphenoid ridge and temporal bone of a 41-year-old woman. The lesion produced hyperostosis of the involved bones, ipsilateral proptosis, and reduced vision for 4.5 years. The radiotherapy yielded little improvement of the exophthalmos and vision. Review of 125 reported meningiomas intimately related to the skull and presenting primarily with hyperostosis and minimal soft tissue component, including the current case, disclosed that all but one affected the cranium proper, particularly the middle ear, temporal bone, frontal bone, and parietal bone. The exceptional one was in the mandible. They tended to occur between the fifth and seventh decades of life with the peak occurrence between the fifth and sixth decades. The average age was 46 years for overall. The female-to-male ratio was 2:1. Six of 125 primary meningiomas closely associated with the skull were malignant and two of these spread to the lungs. The pulmonary metastasis was spontaneous in one case.
