Show Summary Details


A 64-year-old female patient presented with a 16-year history of persistent dry cough that was undiagnosed after workups at several healthcare facilities. The patient denies wheezing, shortness of breath or sputum production. Previous workups include chest imaging, transthoracic echocardiogram (TTE), laryngoscopy, spirometry and bronchoscopy, all of which were unremarkable. During her current evaluation, spirometry was ordered again for the patient, which showed a post-bronchodilator improvement in the FEV1 by 13%, strongly suggestive of asthma. The patient was started on pharmacological therapy for severe persistent asthma, which led to sustained symptomatic improvement per evaluation at follow-up after 2 months. Spirometric findings, clinical presentation and resolution of symptoms with adequate therapy for asthma suggest that this is a case of cough variant asthma that went undiagnosed for several years. This case report summarizes the workup for chronic cough and how the diagnosis of cough variant asthma can be missed.
