Congenital Tracheal Diverticulum

Abstract

A 72 year-old female complained of persistent cough. Fibroptic bronchoscopy and bronchography showed a tracheal diverticulum in the right posterior wall, 33 mm above the carina. It measured 7×10 mm, and the mucosa was smooth and normal in color. This case was considered as a congenital tracheal diverticulum. In Japan, 18 cases have been reported including this case consisting of 14 males and 4 females, and the age ranged from 29 days to 83 years. In almost all cases, the tracheal diverticulum was observed in the right posterior wall. In several cases, inflammatory findings were observed bronchoscopically.
