Sphenoid wing meningiomas represent a difficult to access subtype of intracranial meningiomas involving important neurovascular structures such as the optic nerve, cavernous sinus or carotid artery. They cause neurological compromises by direct compression of adjacent cranial nerves. Insidious and aggressive dural, bony, and orbital involvement produces several difficulties for adequate ...
