Abstract
We have seen two cases of tracheal diverticulum, a comparatively rare disease, which are reported here.
Case 1 was a 36-year-old male whose main complaint was bloody sputum. A diverticulum was found on the right dorsal side 2cm above the tracheal branching region by bronchial fiberscopy. Tracheal cartilage rings and a membranous area were present in the lumen, and a congenital tracheal diverticulum was diagnosed.
Case 2 was an 80-year-old female with coughing and sputum as the main complaints. In laryngofiberscopy, a diverticulum was found on the right dorsal side 3cm subglottically. The aperture was expanded and sacciform, and acquired tracheal pulsion diverticulum was diagnosed.
In both cases, the course of the disease is being observed conservatively.
We discussed 28 cases of tracheal diverticulum reported in the Japanese literature.
