Accepted Answer

Alveolar

Question 22

Alveolar or Interstital lung disease based on CXR findings: line-like (linear, Kerly B lines)

Interstitial

Question 23

Alveolar or Interstital lung disease based on CXR findings: Lungs look coarse, fine reticular, nodular, reticulonodular

Accepted Answer

Interstitial

Question 24

What is Silhouette sign? give some examples of it

Accepted Answer

the border of a normally visible structure is obscured by adjacent pathology.
1.ex: RML pneumonia obscures the right heart border**.
2.ex: Lingular pneumonia obscures the left heart border**.

Question 25

What is air bronchogram sign?

Accepted Answer

Occurs when blood, pus or fluid fills the alveoli providing a background such that air within bronchi becomes visible.

**The air bronchogram is the hallmark of alveolar lung disease

Question 26

What three things can enter/fill the alveoli to cause Airspace disease?

Accepted Answer

1.Blood (pulmonary contusion).
2.Pus (pneumonia).
3.Fluid (pulmonary edema).

Question 27

Alveolar or Interstital lung disease based on CXR findings: Bat Wing/ Butterfly sign

Accepted Answer

Alveolar (pulmonary edema)

Question 28

Alveolar or Interstital lung disease based on CXR findings: Large Hila, Normal heart, Sharp gutters, and indistinct interstitial space

Accepted Answer

Interstitial

Question 29

What is the best way to interpret CXRs?

Accepted Answer

Compare to OLD films

Question 30

CXR findings with COPD

Accepted Answer

1.Hyperlucency.
2.Hyperinflation.
3.Flattening of the hemidiagphragms (FIRST SIGN).
4.Barrel Chest.
5.Rapid tapering of the vasculature.
6.Inc size of RETROSTERNAL CLEAR SPACE.
