title: Tracheal diverticulum: a rare finding in a patient with worsening chronic cough.
abstract: Acquired tracheal diverticulum is a rare clinical entity with only limited reports in the literature. We report a case of a tracheal diverticulum that was identified as part of a work-up for a worsening cough. In this case the diverticulum was observed 2 years after surgical management of a retropharyngeal abscess. It was felt that pooling of secretions in the acquired pouch was a contributing factor in the exacerbation of the patient's chronic cough. Because of the patient's extensive comorbidities, observation and serial computed tomography scans were recommended.
