A rare cause of odynophagia: infected tracheal diverticulum.

: Tracheal diverticulum is a relatively rare lesion. Tracheal diverticula are divided into two subgroups as congenital and acquired with different characteristics and etiologies. The majority of these anomalies is asymptomatic and found as incidental findings on radiological imaging. This article presents a case of an infected tracheal diverticulum presenting with odynophagia. It should be noted that infection may obstruct the air-filled lumen of the diverticulum, causing a diagnostic challenge. Multislice computed tomography with coronal reconstructed images is the modality of choice for diagnosing diverticulum and assessing therapeutic response in associated complications.
