Presentation
The clinical presentation is variable and it can occur in several different age groups. We present the case of a young man who was admitted to the hospital for an asthma exacerbation and was found to have tracheobronchomegaly on his CT scan. [ncbi.nlm.nih.gov]
A case is described which presented as a severe life threatening pneumonia in which the bronchoscopic, radiographic, and computed tomographic findings are given. [doi.org]
This case is being presented due to its rarity and unusual presentation as a single mass lesion arising from the posterior wall of the larynx causing near total obliteration of the tracheal lumen. Financial support and sponsorship Nil. [ijpmonline.org]
Tracheobronchomegaly presents when the defect extends to the central bronchi. [hindawi.com]
In mild cases, patients are asymptomatic or present only with chronic cough and have normal pulmonary function. [orpha.net]

Dyspnea, cough, difficulty in clearing secretions, recurrent bronchitis, pneumonia, and respiratory failure have been reported in patients with the Mounier-Kuhn syndrome.7 These are nonspecific symptoms and are similar to those in patients with chronic [journals.lww.com]

Constitutional Symptom
There were generalized constitutional symptoms of fatigue, malaise and weight loss. The patient had no family history of chronic obstructive pulmonary diseases. He had always been a non- smoker and worked as manual labourer. [jemds.com]
Respiratoric

Bronchial Breath Sounds
Cardiorespiratory examination was significant for bilateral crepitations and occasional bronchial breath sounds. The heart sounds were normal. Hemogram revealed mild anemia (hemoglobin 11.5 g%). [lungindia.com]
Tachycardia, bronchial breath sounds, diffuse expiratory wheezing, and rhonchi were noted on physical examination. Laboratory analysis was significant for leukocytosis (white blood cell count of 12.0 103/µL) with normal procalcitonin ( 0.05 ng/mL). [cureus.com]

Decreased Breath Sounds
Physical examination revealed increased body temperature with decreased breath sound in both lungs with inspiratory crepitations, more pronounced in mid and lower lung field. Finger clubbing was present. [omicsonline.org]

Regurgitation
Associated findings included decreased contractility of RV and moderate tricuspid regurgitation. A diagnosis of acute pulmonary thromboembolism (PTE) was suggested. [lungindia.com]

Hepatomegaly
The physical examination was unremarkable, except hepatomegaly. There was no lymphadenopathy or splenomegaly. Routine laboratory findings revealed low hemoglobin level with elevated serum transaminases and alkaline phosphatase levels. [academic.oup.com]
Workup
The clinical presentation of TO is variable and ranges from incidental diagnosis in asymptomatic patients during workup or management for unrelated medical problems, to devastating disease with central airway obstruction. [utsouthwestern.influuent.utsystem.edu]
For further diagnostic workup bronchoscopy was performed afterwards. How to Cite: Schiettecatte E, Van Hedent E, Van Herreweghe R, Verstraete K. Mounier-Kuhn Syndrome. Journal of the Belgian Society of Radiology. 2015;98(3):139–40. [jbsr.be]
Our case is the oldest female patient described in literature with MKS, indicating that appropriate diagnostic workup may be required in elderly subjects as well. Competing Interests The authors declare that there are no competing interests. [hindawi.com]
Although her HIV has been well-managed, clinical management of future exacerbations could lead to complicated and extensive infectious disease workups. [cureus.com]

The study revealed an air space consolidation involving right upper lobe with air bronchograms appearing as a soft tissue density on soft tissue window [Figure 1] a and [Figure 1] b. [aihbonline.com]

Pseudomonas in the Sputum
We describe a case of an older lady labelled for many years as COAD but who was a lifelong non-smoker and had Pseudomonas in her sputum. A CT of thorax for suspected bronchiectasis revealed tracheobroncomegaly (Mounier-Kuhn syndrome). [ageing.oxfordjournals.org]
Treatment
Management and treatment Treatment is symptomatic. Chest physiotherapy can be proposed to improve mucociliary clearance and antibiotics are administered for treatment of pulmonary infections. [orpha.net]
The treatment of TO is usually symptomatic. with emphasis on the management and prevention of recurrent respiratory infections. [utsouthwestern.influuent.utsystem.edu]
Case reports discussing the choice and efficiency of antibiotic treatment are random. [tandfonline.com]
We report on a group of patients with TO and discuss their presentation and their treatment modalities. [link.springer.com]
Prognosis
Overall prognosis is generally good and is dependent upon airway stenosis caused by nodules. [radiopaedia.org]
Prognosis The impact of this condition on life expectancy has not been evaluated. [orpha.net]
Etiology
Etiology The etiology of tracheobronchomegaly is unknown. Some authors have postulated a congenital etiology Only gold members can continue reading. [radiologykey.com]
The etiologic mechanism remains unknown. Irritants like cigarette smoke and air pollution could act as irritating factors. [orpha.net]
This is the first report which strongly supports granulomatous etiology such as TB as possible etiology for TPO. [lungindia.com]
HRCT not only allows the identification of bronchiectasis, determining the extent and type of the disease, but also allows in some cases the establishment of the etiology of bronchiectasis. 1. Habesoglu MA, Ugurlu AO, Eyuboglu FO. [thoracicmedicine.org]

Pathophysiology
He was then treated according to the guidelines for P. aeruginosa management in cystic fibrosis patients considering the similarities in clinical presentations and pathophysiology of both diseases. [tandfonline.com]
The etiology and pathophysiology of TO are still needed to be found. An association between atrophic rhinitis and TO was reported ( 6 ), but the directly relationship still lacks enough evidence. [jtd.amegroups.com]
This is an incidental finding, since from the pathophysiological point of view there is no causal relationship between idiopathic pulmonary fibrosis and Mounier Kuhn's syndrome. [scielo.org.co]

Prevention
The treatment of TO is usually symptomatic. with emphasis on the management and prevention of recurrent respiratory infections. [utsouthwestern.influuent.utsystem.edu]
Postoperative continuous positive airway pressure to prevent airway collapse followed awake extubation. [dailyrounds.org]
It is important to identify MKS, as early recognition can lead to better management and prevention of complications. Very few cases of MKS with Bronchial Asthma have been reported so far. [ijmrhs.com]
Control and prevention of recurrent infections will prevent progression to irreversible pulmonary fibrosis. Several trials have also shown benefit of continuous positive airway pressure, airway stenting, and tracheobronchoplasty [9]. [cureus.com]
Management: There is no permanent and definitive treatment to prevent the formation of the respiratory nodules. In advanced cases, surgical resection or laser therapy of the nodules may be required. [xpertdox.com]
