Abstract

We report a case of a 32-year-old female patient who presented with decreased vision on both eyes and headache. In fundus examination, both eyes had elevation of the optic disc and star shaped hard exudates in the macula. Magnetic resonance imaging was completely normal except the saccular dilatation of bilateral optic nerve sheath. The patient was treated with oral steroids following high-dose intravenous methylprednisolone. She displayed good anatomical and functional results during the follow-up. This case raises the possibility that optic nerve sheath enlargement, probably induced by an idiopathic inflammatory optic neuritis, may simulate dural ectasia of the optic nerve sheath.
