Unexplained disabling and long-lasting cough: a case report

A 51-year-old woman was referred to our department due to chronic dry cough lasting six years without an etiological diagnosis. The patient suffered from chronic deterioration in her quality of life due to a persistent cough that sounded like a barking seal.

A severe form of malacia involving the inferior third of trachea and the main bronchi was diagnosed. According to our protocol, a self-expandable prothesis was placed in the distal portion of the trachea via rigid bronchoscopy with excellent results in cough relief. The patient was subsequently scheduled for tracheobronchoplastic surgery with a polypropylene matrix. Two and a half years after surgery the patient had a significant improvement in quality of life with a complete resolution of her symptoms.

This report demonstrated that tracheobronchomalacia can be difficult to diagnose with a serious impact on the patient’s life. Referral to a specialized center is essential in the diagnostic and therapeutic management of this disease. Surgical treatment by tracheobronchoplasty may represent a good solution in selected patients.
