Describe the possible association of tracheal diverticula with thoracic trauma and respiratory symptoms. Tracheal diverticula are incidental findingsin sectional studies, most of them seen during tracheostomy, laryngectomy, poor ventilation, trauma follow up and in chronic obstructive pulmonary disease studies. Tracheal diverticula divide into two subgroups: congenital and acquired. The majority are located along the right posterolateral wall of the trachea near the thoracic operculum, between the cartilaginous and muscular portion of the tracheal wall. It is believed that the left paratracheal structures provide a supporting...

We performed a restrospective analysis of 538 chest CT scans requested by the emergency department of our medical center in a time interval from January to December 2014, analyzed by two expert radiologists using Carestream PACS software in a multiplanar reformatted (axial, coronal and sagittal) images with a pulmonary and mediastinal parenchyma window, using a GE tomograph lightspeed VCT model with 5230VCTABC series. The statistical analysis was performed using SPSS V19 software to determine means, percentages and Xi squared.

A total of 538 chest CT scans were analyzed, the mean age was 65.4 years, with a minimum of 3 years and a maximum of 98 years. The gender ratio was 236 (44%) women vs 302 (56%) men. In this study 198 patients (37%) had trauma, and 340 patients had history of respiratory symptoms without trauma. We found that 11 patients (5.6%) with trauma had tracheal diverticula, 9 patients were men and 2 women, compared to 15 patients (4.4%) who had respiratory symptoms without trauma,...

Tracheal diverticula are rare, with an estimated frequency of 1% by autopsy and 0.75-5.2% with computed tomography. Acquired diverticula has been associated with persistent chronic cough by increasing intraluminal pressure in the trachea, resulting in a mucosal herniation through a weakness area of the tracheal muscular wall. Our study demonstrated there is no association between closed and direct trauma (cough) on tracheal epithelium in the development of tracheal diverticula. Despite the slightest difference between the two groups, tracheal diverticula were more frequent in the trauma...
