A previously healthy 36-year-old woman presents to the clinic with 6-month history of episodic dyspnea, accompanied by cough and wheezing. She reports that her symptoms begin and resolve abruptly and have been partially responsive to salbutamol inhaler. Her examination and laboratory work, including spirometry, are all unremarkable.
Which one of the following is the most likely diagnosis?
Inducible laryngeal obstruction (Paradoxical vocal fold motion)
• An inappropriate, transient, reversible narrowing in the larynx in response to external triggers.
• The most common inducers are (exercise, irritants, and emotional stress) or may occur spontaneously.
• The predominant complaint is dyspnea, patients may also report throat tightness, choking sensation, dysphonia, cough, gastroesophageal reflux, or dysphagia.
• It is often mistaken for asthma because it is episodic, and the stridor may sound like wheezing.
• Typically, albuterol has minimal to no beneficial effect.
