Chronic Cough Revealing a Tracheal Diverticulum: A Case Report

Abstract

Tracheal diverticulum (TD) is a rare entity in the literature. It is the consequence of a congenital or acquired weakness of the tracheal wall. The principal difference lies in the histological characteristics of the wall. Most cases are asymptomatic, but when symptoms are found, they are usually not specific. Therefore, the diagnosis is made based on the results of CT. We report a case of a 62-year-old female presenting with a chronic cough. A diagnosis of the TD was established on the basis of a thoracic CT scan.

Tracheal Diverticulum Mimicking Pneumomediastinum: A Case Report Emphasizing the Importance of Differential Diagnosis in Chest Imaging Evaluation

“…While congenital diverticulum is due to developmental failure, the development of an acquired TD is associated with chronic increases in intraluminal pressure, such as in chronic obstructive pulmonary disease (COPD), which leads to the weakening of the tracheal wall [1]. Although TDs are considered benign in nature, they are occasionally symptomatic, presenting with cough, dyspnea, frequent respiratory infections, dysphonia, or hiccups [2][3][4]. Additionally, there have been several reported cases of adverse outcomes associated with TD associated with ventilatory support [5][6][7].…”
