1

Identify the structures shown here

1 - Aortic Arch (should be ~4 cm)

2 - Pulmonary Trunk

3 - Left ventricle

2

What is demonstrated by the yellow lines?

3

What structures are represented by the blue & purple markings?

Blue

4

What condition is likely the cause of these findings?

Pneumonia/Tuberculosis 

5

Identify the structure shown here

Horizontal fissure

6

What pattern of pneumonia is shown here?

- Bilateral, perihilar area, Irregular

- Bronchopneumonia

- Pink circle = cavitation •associated w/ Infection ie. TB & Tumor)

7

This appearance is associated with what condition

Interstitial/Nodular

"Milliary pattern"

Associated with TB or fungal infection 

(Differential = metastasis/tumor)

8

- Opacities frequently desribed as ill-defined, hazy or fluffy

- Margins of opacities are poorly defined & indistinct

- May demonstrate air bronchograms & silhouette signs

Air space disease (aka consolidation)

9

In air space disease, air is replaced with what 4 things

Blood (pulmonary hemorrage)

Pus (exudate assoc. w/ infection)

Water (aspiration)

Cells (tumor)

10

What findings are demonstrated here?

11

What findings are shown here?

12

____ pattern in interstitial disease that appears as lines

Reticular

13

____ pattern in interstitial disease that appears as small numerous discrete opacities separated from one another by normal lung

Nodular

14

_____ pattern in interstitial disease that is a combo of lines & opacities

Reticulonodular

15

What findings are shown here?

16

What findings are shown here?

17

What findings are shown here?

18

When two similar radiographic densities are in anatomical contact with one another, the visible border between the two structures is lost

Silhouette sign

19

Involvement of RUL → what structure silhouetted

Ascending aorta

20

Involvement of RML → what structure silhouetted

Right heart border

21

Involvement of RLL → what structure silhouetted

Right hemidiaphragm

22

Involvement of LUL → what structures silhouetted

Aortic knob

Pulmonary trunk

Left heart border

23

Involvement of LLL → what structures silhouetted

Descending aorta

Left hemidiaphragm

24

What findings are shown here?

Silhouette Sign - Increased density in RML which obscures right heart border

25

What findings are shown here?

Silhouette Sign - LUL density is obscuring left heart border

26

What findings are shown here?

Silhouette sign - LLL density obscuring left hemidiaphragm

27

- Visualization of air in bronchi due to surrounding lung tissue (alveoli) filling w/ fluid or cells

- Bronchi should not normally be seen

Air bronchogram

28

Air bronchogram sign is primarily associated with

Consolidation/Air space disease

29

What findings are shown here?

30

What findings are shown here?
