- Evaluation of Tracheal and Main Bronchial Diverticula Using Thin-Section MDCT
- Abstract
- Purpose
To evaluate the characteristics of tracheal and main bronchial diverticula in relation with emphysema.
Materials and Methods
A total of 967 CT images were reconstructed with 1.25 mm axial images over 2 months. The incidence, size, number, and location of the tracheal and main bronchial diverticula were analyzed using 3D medical software (Seoul, Korea). The incidence of emphysema and the relationship between emphysema and the size of the diverticula were analyzed.
Results
In total, 50 patients (5.1%) showed tracheal diverticula in the right posterolateral wall. In addition, 51 patients (5.2%) showed 89 (9.4%) main bronchial diverticula in the inferior wall, while 68 (72%) showed diverticula in the left posterolateral wall. Tracheal diverticula (6.4 ± 5.0 mm, 1.0 ± 0.2) were larger and fewer than the main bronchial diverticula (2.1 ± 2.0 mm, 1.8 ± 1.6) (p<0.05). Moreover, tracheal diverticula (10.3 ± 7.4 mm) with emphysema in 13 patients (26%), were larger than those without emphysema (5.1 ± 3.0 mm) (p<0.05).
Conclusion
On thin-section MDCT, the rates of incidence for tracheal and main bronchial diverticula are about 5%, respectively. Tracheal diverticula in the right posterolateral wall are smaller and fewer than the main bronchial diverticula, which are located primarily in the inferior wall of the left bronchus. Tracheal diverticula with emphysema are larger than those without emphysema.
