Presentation
Patients with a history of cough underwent a ct scan of lungs
Patient Data
The axial CT and coronal CT images show an elongated paratracheal air cyst measuring about 26x16 mm in the right posterolateral aspect of the trachea at the level of the thoracic inlet. A suspect communicating channel with the trachea is only visible in the mediastinum window.
Localizer image shows the presence of an ovoid cyst on the right side of the trachea.
Case Discussion
A tracheal diverticulum is frequently noted as an incidental finding on CT scan of the lung. Most cases are asymptomatic, but when symptoms are present, it usually has airway symptoms with cough or recurrent respiratory infection.
It has a slight female predilection and is most commonly found in patients in the sixth decade of life.
It is located in the right posterolateral aspect of the trachea at the thoracic inlet level, and it is mostly 3–10 mm in size and elongated in shape.
