Multiple sacculations were noted in the proximal part of thoracic part of trachea involving posterolateral walls (Figure 2& 3).
On further evaluation computed tomography scan of the chest (plain) revealed dilated trachea and mainstem bronchi with multiple sacculations in the proximal part of thoracic part of trachea involving posterolateral walls with tractional and tubular bronchiectasis in bilateral lung fields which confirms it as a case of Mounier-Kuhn syndrome which is a rare cause of bronchiectasis and should be considered in differentials of lower respiratory tract infections.
The CT scan report mentioned, "The patient is having tracheal stenosis of 12mm, which is extending in thoracic part of trachea
. It is almost completely occluding the lumen of the trachea." ENT consultation was done and the patient was shifted to cardiothoracic surgery for the sleeve resection of the trachea.
