Abstract

Tracheomalacia is one of the rarest etiologies of chronic cough. Herein, we present the case of an elderly woman with chronic cough who on detailed evaluation was found to have focal (localized) tracheomalacia due to compression by an aberrant right subclavian artery (arteria lusoria). The absence of dysphagia in this patient also deserves particular mention.
