Síndrome de Susac: reporte de caso.

Objective. To describe the case of a 23 year-old female patient disoriented in space and time, with an oppressive left-sided temporal headache, associated with ataxia, and bradypsychia. Methods. A possible multiple sclerosis associated to the clinical and paraclinical tests was suspected at the beginning. An acute disseminated encephalomyelitis was suspected and treated with methylprednisolone pulses and patient was discharged. Within a month, she required again due to exacerbation of neurological symptoms given by a loss of strength in upper and lower limbs, dysarthria, wetting, and drowsiness. Devic's disease was diagnosed initially. Because response to corticosteroids was not the expected, it was decided to treat with plasmapheresis; in addition, new tests were requested to rule out the suspected disease. Results. Treatment was focused on a possible diagnosis of Susac's syndrome with an arteriography retinal test and potential auditory evoked. [ABSTRACT FROM AUTHOR]
