Abstract:
A 56-year-old man whose chest radiograph in 1993 was normal was referred to our hospital because of a productive cough in 1997. Chest radiographs showed a thin-walled cavity filled with air. We followed his condition radiographically for three years and observed enlargement of the diameter of the lesion and appearance of an air fluid level, and we therefore decided to perform thoracoscopic middle lobe resection in 1999. Histological examination showed a communication between the cavity and a bronchus. As far as we know, there are no previous reports about intrapulmonary bronchogenic cysts which on radiographic observation developed from negative findings to a thin-walled cavity filled with air over a 6-year period.

The Bronchial Tree
The trachea, commonly known as the windpipe, is a tube that connects the larynx (voice box) to the bronchi. At a point called the carina, it bifurcates into two primary bronchi. The right primary bronchus is wider, shorter, and more vertical than the left primary...
