A case of meningioma involving the optic nerves,optic chiasm,and optic tracts at presentation is reviewed.Computed tomography showed the chiasm to be engulfed by tumor,and this finding was helpful in differentiating this lesion from an optic chiasm glioma.Magnetic resonance further characterized the lesion by demonstrating the presence of a cystic component along the lateral aspect of the mass. |
