Findings:
Avid homogenous contrast enhancement of the sphenoid wing mass measuring approximately 3 x 1.4 cm in the axial images, extending into the extra-conal space on the right side and causing mild right-sided proptosis. Medial displacement of the lateral rectus from the sphenoid wing mass.
There is enhancement and thickening of the dura overlying the right temporal pole and the orbital surface.
No obvious compression of the optic nerve. No invasion of the cavernous sinus.
No significant mass effect and peri-tumoral edema in the right anterior temporal lobe.
Few non-specific foci of T2/flair hyperintensity are seen in bilateral cerebral hemisphere. The brain parenchyma is otherwise unremarkable. No further enhancing lesions could be identified.
The pituitary gland is normal.
Intracranial circulation is unremarkable.
Minimal fluid is seen in several mastoid air cells in the left mastoid process. The mastoid air cells on the right are clear. Minimal mucosal thickening is seen in the left maxillary sinus. The paranasal sinuses are otherwise clear.
Conclusion:
Imaging features characteristic of a right-sided sphenoid wing meningioma with extension into the right extraconal space and mild right-sided proptosis.
