Presentation
Left eye proptosis.
Patient Data
Expansion, thickening, extensive sclerosis and hyperostosis involves the left sphenoid wing and to less extent the squamous portion of the temporal bone
Associated extra-osseous left intra-orbital small soft tissue component is seen near the orbital apex compressing and displacing the optic nerve medially.
Subsequent left proptosis is noted.
Case Discussion
Sphenoid wing meningioma is a meningioma that occurs near the sphenoid wing. "En plaque meningioma" represents a group of meningiomas known by its particular sheet-like dural involvement and its disproportionately large bone hyperostosis.
These tumors are mainly a bone disease, as their symptoms and prognosis are influenced mostly by the extension of bone invasion instead of intradural involvement.
