Posterior Tracheal Diverticulosis Karan Madan, MD, DM,* Chandan J. Das, MD,w and Randeep Guleria, MD, DM* Summary: Multiple tracheal diverticulosis is a rare clinical entity. Tracheal diverticula are usually recognized radiologically as solitary right paratracheal air collections on thoracic computed tomography examination. They are usually asymptomatic but can occasionally present with persistent symptoms. We herein report the case of a 50-year- old male patient who underwent extensive evaluation for persistent cough. Multiple posterior right paratracheal air collections were recognized on thoracic multidetector computed tomography examination, which was confirmed as multiple-acquired poste- rior upper tracheal diverticula on flexible bronchoscopy. The patient improved with conservative medical management. Key Words: tracheal diseases, diverticulum, bronchoscopy, cough, tracheal diverticulum, posterior tracheal diverticulosis (J Bronchol Intervent Pulmonol 2014;21:338–341) FIGURE A.

T racheal diverticulosis is a benign condition characterized by single or multiple tracheal wall invaginations mostly found incidentally on post- mortem examinations. These are usually recognized incidentally on thoracic computed tomography (CT) as right paratracheal air collections. The con- dition is mostly asymptomatic; however, in symptomatic patients, a number of symptoms usually pertaining to the upper airway have been described.
