Tracheocele--a case report.

A tracheocele is a rarely encountered entity that may be congenital or acquired. This tracheal lesion is characterized by the presence of a single cystic pouch filled with air or a mixture of liquid and air. We recently managed a case of a large voluminous acquired tracheocele originating from the right posterolateral tracheal wall. A 39-year-old male patient presented with chronic cough and breathy voice. Rigid laryngoscopy revealed a right immobile vocal fold. Computed tomography scan revealed a tracheocele that was excised externally with recurrent laryngeal nerve preservation.
