Vocal cord paralysis as a presenting sign in the Shy-Drager syndrome.

A 70-year-old patient with bilateral vocal cord paralysis, accompanied by inspiratory stridor and increased snoring, is presented. Respiratory dysfunction, deteriorating over 18 months, necessitated permanent tracheostomy. Only two and a half years after the onset of symptoms the patient developed extrapyramidal signs combined with severe autonomic failure, suggesting a diagnosis of Shy-Drager syndrome. Vocal cord palsy preceding any other neurological or autonomic manifestations of that syndrome has been infrequently described. This diagnosis should be considered in cases of vocal cord palsy of undetermined etiology, especially when associated with increased snoring or episodes of sleep apnea.
