Observations on massive collapse of the lung and on other clinical conditions presenting extensive atelectasis enable us to offer a more complete description of the characteristic roentgen-ray shadow cast by a single atelectatic lower lobe, and to call attention to its association with certain cases of chronic pulmonary suppuration. Lobar atelectasis has been identified by Manges1 through roentgen-ray observations in cases of obstruction of the air passages by foreign bodies. It has been observed in postoperative massive atelectasis of the lung by Jackson and Lee2 and by Churchill.3

ROENTGEN-RAY OBSERVATIONS IN LOBAR ATELECTASIS  A deflated lobe of the lung is commonly pictured as a small puckered mass retracting to the hilum by means of a bellows-like shortening of the bronchi. This is what happens when the deflation occurs as the result of pneumothorax or pleural effusion; but when it is produced by bronchial obstruction in a chest
