Introduction: Susac syndrome (SuS) is a disease manifested as the clinical triad of encephalopathy, branch retinal artery occlusion, and loss of sensory neural hearing.
Case report: The case is presented of a 28-year-old patient hospitalized due to visual impairment of the left eye, and whose hearing and neuropsychiatric disorders had appeared two years earlier. Magnetic resonance imaging demonstrated lesions located in the white matter and along the corpus callosum. An audiogram showed bilateral sensory neural hearing loss. Fluorescein angiography examination revealed branch retinal artery occlusion of the left eye. Based on the clinical picture and results of tests, the diagnosis of SuS was made. Despite the use of steroid and immunosuppression therapy the disease progressed.
Conclusions: The prognosis for SuS depends on the early diagnosis and implementation of treatment. It should be underlined that in case of hearing loss or encephalopathy of unknown cause, SuS should always be excluded.
