• A 35-year-old man was initially seen following the incidental discovery of swollen optic discs in both eyes. Over a subsequent 15-year period, the patient experienced an inexorable loss of vision in both eyes, characterized by normal neuroradiologic findings and the presence of opticociliary shunt vessels on both discs. A craniotomy ultimately demonstrated the presence of bilateral optic nerve sheath meningiomas that appeared to have arisen multifocally.
