MDCT and virtual bronchoscopy findings of tracheabronchomegaly

Full text: Introduction: Tracheabronchomegaly (TBM) or Mounier-Kuhn syndrome is a rare syndrome which is characteristic with bronchiectasis, recurrent respiratory tract infections with expansion of large bronchi. Respiration function test, imaging methods and bronchoscopy are used for the diagnosis. Objective and tasks: We aimed to evaluate the findings of virtual bronchoscopy and MDCT of 21 years-old male patient who has complaint of recurrent lower respiratory tract infection. Materials and methods: We perform thorax CT and virtual bronchoscopy with 320-detector multidetector computer tomography. Results: Diameter of the trachea at the carina level was 30.5 mm, in turn the diameters of the right and left main bronchi were 18 mm and 17 mm. There were moderate bronchiectasis in the middle and lower zones. Conclusion: MDCT and fiberoptic bronchoscopy have been used for the diagnosis of TBM. In such cases, virtual bronchoscopy is non invasive method for demonstrating luminal pathologies
