Two different causes of lung collapse and the difference in their radiologic appearance.

A, There is atelectasis of the entire right lung (solid black arrow) from an obstructing endobronchial lesion. The visceral and parietal pleura remain in contact with each a. Other mobile structures in the mediastinum, such as the trachea and right main bronchus (dotted black arrows), shift toward the atelectasis. The left lung overexpands and crosses the midline (solid white arrow).

B, This patient has a large right-sided pneumothorax. Air (solid white arrow) interposes between the visceral (dotted white arrows) and parietal pleurae, causing the lung to undergo passive atelectasis (solid black arrow). A chest tube is seen in the right hemithorax (arrowhead) that had been removed from suction.

Notes：

【Obstructive atelectasis versus a pneumothorax 阻塞性肺不张vs气胸】

肺萎陷的两个不同病因。支气管内病变致支气管阻塞，整个右肺不张。脏壁胸膜紧贴。纵隔内其他结构，像气管和右主支气管，均向患侧移位。左肺过度充气膨胀，越过中线。

右侧大量气胸患者，气体游离在脏壁胸膜之间，引起被动性（压力性）肺不张。右胸可见胸导管，用于引流。
