ABSTRACT
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) is a rare disease of unknown etiology characterized by abnormal pathologic dilatation of tracheabronchial tree. The diagnosis of MKS is normally made on CT scan of chest on the basis of enlarged diameters of trachea and main stem bronchi. We are presenting histologically confirmed case of MKS, where the diameter of right main bronchus is below minimum diameter (mean+3 SD) required for the diagnosis. We suggest that the diagnosis of MKS should not be solely based on fixed criteria such as the diameter of airways, but on the basis of the overall clinical, pathologic, and radiologic profile.

Mounier-Kuhn syndrome is a rare clinical entity. It was described in 1932 to refer to the presence of tracheobronchomegaly. 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. A review of the literature for this rare, but interesting, phenomenon is included.
