![]() | Media file 1: Atelectasis. Left lower lobe collapse. The opacity is in the posterior inferior location. |
![]() | Media file 2: Atelectasis. Loss of volume on the left side; an elevated and silhouetted left diaphragm; and an opacity behind the heart, called a sail sign, are present. |
![]() | Media file 3: Atelectasis. Left upper lobe collapse showing opacity contiguous to the aortic knob, a smaller left hemithorax, and a mediastinal shift. |
![]() | Media file 4: Atelectasis. CT scan of a left upper lobe collapse with a small pleural effusion. |
![]() | Media file 5: Complete atelectasis of the left lung. Mediastinal displacement, opacification, and loss of volume are present in the left hemithorax. |
![]() | Media file 6: Atelectasis. Right lower lobe collapse. |
![]() | Media file 7: Atelectasis. Both right lower lobe and right middle lobe collapse. The left lung is hyperexpanded. |
![]() | Media file 8: Complete right lung atelectasis. |
![]() | Media file 10: Atelectasis. The left upper lobe collapses anteriorly on a lateral chest x-ray film. |
![]() | Media file 11: Atelectasis. Left upper lobe collapse. The top of the aortic knob sign is demonstrated. |
![]() | Media file 12: Atelectasis. Left lower lobe collapse. |
![]() | Media file 13: Atelectasis. Right middle lobe collapse shows obliteration of the right heart border. |
![]() | Media file 14: Atelectasis. The azygous lobe of the right lung may be mistaken for a collapsed right upper lobe. |
![]() | Media file 15: Atelectasis. Left lower lobe collapse. The sail sign is obvious. |
![]() | Media file 16: Atelectasis. Left upper lobe collapse. The Luft Sichel sign is demonstrated clearly in this radiograph. |
![]() | Media file 17: Atelectasis. Chest CT scan showing left upper lobe collapse. |
![]() | Media file 18: Atelectasis. The right lower lobe collapses inferiorly and posteriorly. |
![]() | Media file 19: Atelectasis. Right lower lobe collapse without middle lobe collapse, the right major fissure is shifted downward and is now visible. |
![]() | Media file 20: Atelectasis. Right upper lobe collapse demonstrating Golden sign of S. |
![]() | Media file 21: Atelectasis. Right middle lobe collapse showing obliteration of the right heart border. |
![]() | Media file 22: Atelectasis. Right middle lobe collapse on a lateral chest x-ray film. |
![]() | Media file 23: Atelectasis. Right upper lobe collapse and consolidation. |
![]() | Media file 24: Atelectasis. Right upper lobe collapse. |
![]() | Media file 25: Atelectasis. Right upper lobe collapse. |
![]() | Media file 26: Atelectasis. Left lower lobe collapse on posteroanterior view. |
![]() | Media file 27: The left lower lobe collapses toward the posterior and inferior aspects of the thoracic cavity; the atelectatic left lower lobe is present as a sail behind the cardiac shadow. |
