1. Enhancing mass is seen which causes parallel thickening of the left optic nerve sheath as described above likely representing an optic nerve sheath meningioma, possibly increased in size from the prior exam.
2. Incidentally noted small enhancing focus in the left internal auditory canal which may represent a small vestibular schwannoma.
3. Nonspecific, periventricular and subcortical T2/FLAIR white matter hyperintensities, not significantly changed compared to prior
(Optic nerve sheath meningioma)
