16
Q
A

Atelectasis: upward displacement of minor fissure due to RUL collapse w/ mediastinal silhouette sign.

17
Q
A

Resorption atelectasis of LUL caused by tumor compressing airway; tracheal/mediastinal shift towards collapse

18
Q
A

LLL pneumonia; consolidation w/ silhouette sign

19
Q
A

Consolidation due to cardiogenic pulmonary edema (silhouette sign)

20
Q

Atelectasis vs. consolidation?

A

Both produce airless lung; atelectasis causes decreased lung volume, while consolidation does not.

21
Q
A

air bronchogram: seen with consolidation or atelectasis

22
Q
A

Interstitial fibrosis: perilymphatic interstitial fluid, forming Kerley B lines in secondary septations between lobules.

23
Q
A

Pulmonary fibrosis, causing reduced lung volume

24
Q
A

emphysema

25
Q
A

Pleural effusion: opacity spanning enitre chest, loss of RML volume due to compression, and meniscus

26
Q
A

sarcoidosis

Sarcoidosis: adenopathy

28
