title: [Sphenoid ridge hyperostosis meningiomas "en plaque"].
abstract: We report the cases of two women who underwent surgery for radical resection of sphenoidal hyperostosing meningiomas "en plaque". Outcome was excellent seven and eight years after surgery. The removal of such osseous sphenoidal lesions has always been accompanied by high rates of morbidity, mortality and recurrence. With new surgical approaches and greater exposure of the skull base, interest is again being directed toward complete resection of these rare tumors, which involve scarce intradural but extensive bone invasion.
