case_images: Gadolinium-enhanced magnetic resonance (MR) images. A : Preoperative MR image revealing the mass extended toward the middle fossa laterally and to the sphenoid sinus anteriorly. This lesion also extended to the cerebellopontine angle posteriorly with a compression of the brain stem. B : Postoperative MR image revealing resolution of the mass over the cavernous sinus region sinus.
