Bacterial tracheobronchitis is an extremely rare entity, which was long considered to be a pediatric disease. We report the case of a 65-year-old woman who presented with persistent wheezing, worsening productive cough and sore throat. Computed tomography of the chest revealed the presence of tracheomalacia, confirmed at bronchoscopy. The presence of purulent exudate, coating the trachea and main bronchi, was consistent with bacterial tracheobronchitis. Culture of the tracheal aspirates grew methicillin-resistant Staphylococcus aureus (MRSA). As the patient was afebrile and not systemically ill, the clinical picture was consistent with exudative tracheobronchitis. To our knowledge, this is the first case of MRSA exudative tracheobronchitis and tracheomalacia in a non-ventilated adult. Other adult cases of bacterial tracheobronchitis and MRSA tracheobronchitis in mechanically ventilated patients reported in the literature are also reviewed.Physicians should be aware of the diagnosis of tracheomalacia in adults, which can masquerade as persistent asthma and may be associated with the development of serious infections including MRSA tracheobronchitis.
