Spheno-orbital meningiomas are usually secondary lesions of the orbit and associated with en plaque meningiomas of the lateral sphenoid wing that have extension into the orbit. These tumors can involve the orbital apex with associated hyperostosis compressing the contents of the orbit and optic nerve. Speheno-orbital meningiomas are more common in females. The most common presenting complaints are proptosis, orbital pain and progressive visual loss. Magnetic resonance imaging is the imaging modality of choice for the radiological workup of suspected spheno-orbital meningiomas and offers fine anatomic resolutions of the tumor and orbital morphology. Computed tomography imaging can play a special role in defining hyperostosis of the sphenoid bone and orbit.

The primary goal of surgery is total removal of the tumor, with improvement or preservation of the preoperative visual status. Recent advances in skull base approaches such as modern imaging techniques have allowed surgeons to be more aggressive with primary resections of these tumors.
