A sizable extra-axial mass noted at the right middle cranial fossa measuring 2.9 x 3.7 x 4.3 cm at its largest dimensions, seen lying upon the right sphenoid ridge. It displayed well-defined outlines and homogeneous T2/T1 isointense matrix to the brain. It shows intense post contrast enhancement as well as enhancing dural tail. it is abutting the sphenoorbital fissure. Mild mass effect upon the right temporal lobe with no perifocal edema
This case demonstrates strong radiological features in keeping with a sphenoid wing meningioma involving the region of the anterior clinoid, adjacent medial sphenoid wing, superior orbital fissure, and cavernous sinus.
It exerts a compressive effect on the adjacent skull foramina as compression on the optic nerve.
Tumours in this region can slowly extend to the orbit resulting in slowly progressive proptosis and visual disturbance. They are also associated with sphenoid wing hyperostosis in many cases.
