A case of vocal cord dysfunction in the emergency department

Abstract

We describe the case of a 78-year-old woman admitted to our emergency department for an acute onset of severe dyspnoea with inspiratory wheezing-like sounds. She denied fever, cough, voice change and pain. She referred a similar but less severe episode occurred spontaneously one year before, with complete resolution in few minutes without sequelae. On examination upper airway obstruction was firstly excluded. She was initially treated as having asthma, without response. Parenteral high dose corticosteroids and antihistamines provided no benefit. Point-of-care-ultrasound resulted normal. Flexible laryngoscopy during the episode showed paradoxical vocal cord movement with adduction during both inspiration and expiration. This demonstrated that her dyspnoea was from Vocal Cord Dysfunction (VCD). VCD completely solved after administration of intravenous benzodiazepines.
