A 43-year-old woman presents with painless loss of vision in her left eye. She has decreased visual acuity, an afferent pupillary defect, slight proptosis and disc swelling, implying an optic nerve lesion. Computerized tomographic scanning shows generalized enlargement of the posterior orbital optic nerve. A presumed diagnosis of an optic nerve sheath meningioma is made. The discussion deals with the problems of rational treatment.
