[Susacs syndrome: case report].

We present the case of a 34-year-old woman with clinical picture suggestive of Susacs syndrome, or retinocochlear vasculopathy. This syndrome, which was described for the first time in 1979, is characterized by a clinical triad of encephalopathy, neurosensorial deafness and visual deficit. Its pathogenesis and treatment are still disputed. We have called special attention to differential diagnosis, since this entity has not yet been described in Brazil, and is probably underdiagnosed.
