Sphenoid wing meningioma

Case contributed by Dr Ian Bickle

Presentation

Proptosis of the right eye.

Patient Data

Age: 64
Gender: Female
Modality: CT

Well-defined enhancing 4.8 cm mass centred on the right wing of sphenoid with a significant component of this within the infratemporal fossa. The M2 segment of the MCA abuts the mass medially.

The mass extends through the superior and inferior orbital fissures into the intra and extra-conal spaces. This mass compresses and displaces the optic nerve and lateral rectus muscle, globe with a resultant proptosis.

The right sphenoid wing is hyperostotic and in places elements upto 1.5 cm are completely destroyed.

No extension into the cavernous sinus.

Case Discussion

The sphenoid wing is a relatively common site for a meningioma.

The imaging characteristics are like those elsewhere in the brain, with avid homogenous contrast enhancement and involvement of the underlying bone.
