The case presents a 43 years old man, cigarette smoker, exposed to wood dust at work, with chronic, ineffective cough symptoms, limited physical exertion and recurring respiratory system infection. Disorders appeared at the age of 33 after severe double-sided pneumonia. Despite the lack of active clinical infection the following microorganisms: Pseudomonas aeruginosa and Staphylococcus aureus MSSA were isolated from patient bronchi mucus. Diagnosis followed image examination (CT, virtual bronchofibroscope). The following was recommended: quitting smoking, avoiding dust exposure at work, physiotherapy to ease mucus removal from bronchi and preventive vaccination. Tracheobronchomegaly consists in trachea clearance and central bronchi widening which disturbs air flow in air-passages and decreases cough effectiveness. Main symptoms are: paroxysmal cough, recurring bronchi inflammation and pneumonia resulting in mucus residing in air-passages.

Mounier-Kuhn syndrome, also known as tracheobronchomegaly, is a rare clinical and radiological condition characterized by tracheobronchial dilatation and recurrent respiratory infections. Patients may be asymptomatic or present with severe respiratory illnesses. A CT scan is sufficient to confirm the diagnosis.

Mounier-Kuhn syndrome (MKS) or tracheobronchomegaly is an uncommon disease of the central airways. It is characterized by pathological dilatation of the trachea and main bronchi and inevitably leads to recurrent respiratory infections, bronchiectasis, hospitalizations, and results in considerable morbidity and mortality. Despite numerous case reports, there is a shortage of evidence on clinical outcomes and limited data on interventions, thus presenting a significant gap in the literature.

Tracheobronchomegaly (TBM) is a rare condition characterized by the dilatation of the trachea and bronchi due to severe atrophy of elastic fibers, accompanied by the thinning of the muscularis mucosae and the development of diverticula between cartilaginous rings. The etiology of this condition remains unclear. Tracheobronchopathia osteochondroplastica (TO) is another uncommon airway disease with an unknown etiology.
