Susac's Syndrome in a 27-Year-Old Female.

A 27-year-old woman was referred by the neurologist for ophthalmic examination. She had a history of headache, visual loss in her right eye, four-limb paresthesia, and behavioral changes over the previous 10 months. The patient complained of tinnitus and hearing loss for two weeks. The patient was initially diagnosed with multiple sclerosis, but auditory and retinal involvement (small branch retinal artery occlusion in fluorescein angiography) raised the possibility of Susac's syndrome.
