A Case of Vocal Cord Dysfunction Masqueraded as Exercised-Induced Asthma

Vocal cord dysfunction (VCD) is respiratory disorder characterized by paradoxical closure of the vocal cord during the respiratory cycle leading to obstructive airway symptoms. The clinical presentation of VCD is often dramatic and its misdiagnosis as asthma or exercise-induced brochospasm(EIB) has led to inappropriate treatment including high dose corticosteroids, intubation, and tracheostomy. Many VCD patients are asymptomatic at rest and require exercise challenge to elicit symptoms and vocal cord abnormalities. The "gold standard" for the diagnosis of VCD remains laryngoscopy or bronchoscopy with direct visualization of paradoxical adduction of the vocal cords. We report a case of exercise-induced Vocal cord masqueraded as exercise-induced asthma unresponsive to corticosteroids. And bronchodilator confirmed by typical bronchoscopic findings with paradoxial adduction of the vocal cords.
