Bitonal wheezing and dull cough

Specialty: Respiratory.

  • double-tone cough with dull whistling
  • complex obstructive tumor mediastinal cough

Why it occurs

  • Central bronchogenic carcinoma of the right upper lobe that simultaneously invades the anterior and middle mediastinum (destructively injuring the right recurrent laryngeal nerve, causing a dull bitonal cough due to paralysis of the ipsilateral vocal cord, and partially obstructing the right main bronchus due to extrinsic compression, generating a concomitant dull expiratory wheeze)
  • Large metastatic mediastinal lymphadenopathy that simultaneously compresses the recurrent nerve and the right main airway.

Initial workup

Computed tomography (CT) of the neck and chest with intravenous contrast; Magnetic resonance imaging (MRI) of the mediastinum; flexible nasofibrolaryngoscopy; Flexible bronchoscopy with ultrasound-guided bronchial and transbronchial biopsy (EBUS); Forced spirometry and arterial blood gases.

red flags

Presence of asphyxiating dyspnea at rest, persistent severe chest pain, massive hemoptysis, cyanosis, or inspiratory stridor suggesting critical tracheobronchial obstruction.

Standard management

  • Bronchodilator treatment is symptomatic support: Salbutamol — 100-200 micrograms inhaled as needed
  • Methylprednisolone — 40 mg intravenously every 12 hours in case of peritumoral edema
  • Definitive treatment is emergency oncology or endoscopic palliation with a tracheobronchial prosthesis.
