Sphenoid wing meningiomas.

Meningiomas that arise from the dura along the sphenoid wing can occur in globoid or en plaque forms. Radiographically they can be defined as occurring in the medial, middle, or lateral portions of the sphenoid wing. The medial group carries the highest neurologic risk for surgical treatment, while the hyperostosing en plaque type is the most difficult to remove completely because of orbital and bone involvement. This chapter addresses the clinical presentation and surgical treatment of sphenoid wing meningiomas with an emphasis on the most recent results from the literature.
