[Miller Fisher syndrome: report of a case]

The authors report a case of a 27 year old male patient who has exhibited external ophthalmoplegia, anisocoria, ataxia, absent deep reflexes, dysphagia, dysphonia, bilateral peripheral facial paralysis, hypopallesthesia and a mild sensory impairment of the four extremities. In addition, his cerebrospinal fluid showed albuminocytologic dissociation. The otoneurologic examination showed important findings. These symptoms began ten days after a "cold", and quickly subsided after prednisone therapy. Two months after the onset of clinical features, just a deep apendicular areflexia was detected on his neurological examination. The neurological signs and complementary laboratory findings suggest that both central and peripheral alterations are responsible for the clinical manifestations.
