RESUMO
El síndrome de Mounier-Kuhn o traqueobroncomegalia constituye una rara entidad clínica y radiológica caracterizada por una dilatación de la tráquea y los bronquios principales. Puede asociarse con estructuras saculares en las membranas intercartilaginosas (diverticulosis traqueal), bronquiectasias e infecciones respiratorias a repetición. Las formas de presentación clínica son variables. Tiene una prevalencia entre el 1-4,5 por ciento de la población y se presenta, mayoritariamente, en hombres con un amplio rango etario que oscila entre los 20 y 50 años de edad. Se presenta el caso de un paciente masculino de 77 años con cuadros de infecciones respiratorias bajas a repetición desde la juventud. Luego de realizarle estudios de imagen y broncoscopia, se llegó al diagnóstico de síndrome de Mounier-Kunh. Recibió tratamiento antibiótico inmediatamente y su evolución fue de manera satisfactoria(AU)
Mounier-Kuhn syndrome or tracheobroncomegaly is a rare clinical and radiological entity characterized by dilatation of the trachea and the main bronchi. It can be associated with saccular structures in the intercartilaginous membranes (tracheal diverticulosis), bronchiectasis, and recurrent respiratory infections. The forms of clinical presentation vary. It has a prevalence between 1-4.5 percent of the population and it occurs mainly in men, widely ranging ages between 20 and 50 years of age. We report the case of a 77-year-old male patient with recurrent lower respiratory infections since his youth. After performing imaging studies and bronchoscopy, he could be diagnosed with Mounier-Kunh syndrome. He immediately underwent antibiotic treatment and his evolution was satisfactory(AU)

Mounier-Kuhn syndrome (MKS) or tracheobronchomegaly includes clinical and radiographic findings of tracheobronchial dilatation and recurrent respiratory infections. MKS is a very rare pathology, especially in the paediatric age group which makes it a diagnostic challenge. A 4-year-old girl suffered from dyspnea, recurrent respiratory infections and joint pain. Chest radiography detected peribronchial reinforcement and CT-scan revealed extended tracheal dilatation and bronchiectasis. In addition to MKS our patient was diagnosed with juvenile idiopathic arthritis (JIA) and scleroderma. MKS can be caused by congenital disorder or acquired aetiology. Several connective tissue diseases have been associated with MKS but no cases of JIA or scleroderma are described previously. Our case illustrates that patients who suffer from recurrent respiratory infections with unsatisfactory evolution and unspecific chest X-ray alteration, MKS always has to be considered in the differential diagnosis particularly in patients who suffer from connective tissue diseases.
