A 48-year-old woman noted progressive, painless visual loss in her left eye. She was diagnosed with bilateral optic nerve sheath meningiomas (ONSMs), extending across the planum sphenoidale. Radiation was offered, but the patient declined. She has been followed for more than 27 years with stable visual function and neuroimaging findings. Bilateral ONSMs, although usually described as aggressive in nature, may follow a stable clinical course.
