4
Q

10 steps for Review of Basic Structures for Chest Films

1) Diaphragm domes ok?
2) Pleura NOT thick?

5) Mediastinum is NOT enlarged?
6) Narrow Tracheal band?
7) Hili are NOT enlarged?
8) Normal Cardiac Silhouette?
9) Skeleton parts normal?
10) Soft tissue of the chest wall normal?`

5
Q

Pathology

A

Right Upper Lobe Pneumonia

6
Q

Pathology

A

Azygous Fissure

-Right increased “teardrop” shape lateral to the midsternum

7
Q

Air-space or interstitial disease of the lung?

A

Air-space

  • Can NOT see accentuated thickening of the connective tissues of the lung field (like a leafless tree)
  • Overall appearance is dull and hazy (like a bush) which indicates air-space disease and NOT intertitium disease
8
Q

Is this an air-space disease or interstitial lung disease?

A

Interstitial Lung Disease

  • Accentuation of the connective tissue structures (Fibrosis) leads to a leaf less tree appearance
  • No general soft dullness throughout the lung field rules out air space disease (look for a bush)
9
Q

Is this an interstitial or air-space pattern of lung disease?

A

Interstitial

  • “Leaf less Tree” appearance
  • Air-space would be a “bush like” appearance
10
Q

Air space of interstitial pattern of lung disease?

A

Air-Space

  • “Bush like” appearance
  • NOT “Leaf less tree” like appearance
11
Q

What Sign is seen on the X-ray that indicates a pathology is present?

A

Silhouette Sign

  • Loss of a normal radiodense border secondary to a radiodense pathology positioned contiguous with the normal structure
  • Difficult to appreciate the right heart border = + Silhouette Sign
12
Q

Radiographic Sign

A

Silhouette Sign

-Left cardiac border

13
Q

Significant Finding

-What is a likely cause?

A

Complete loss of costophrenic angle bilaterally

  • Means there is probably significant pleural effusion
  • Lateral Chest will show no posterior costophrenic angle as well (always first to fill up)
14
Q

What Sign can help us locate if this tumor is in the anterior or posterior part of the lung?

-Is this mass in the anterior or posterior lung?

A

Cervicothoracic Sign

-If seen above the clavicles = located in the posterior part of the lung

This mass is above the clavicles, so it must be located in the posterior part of the lung

15
Q

Sign (Black arrows)

-What does it indicate?

A

Air Bronchogram Sign

  • If the lung is filled with a water-based pathology, the air filled bronchi appear radiolucent densities in the middle of the radiodense fluid filled lung. (normal = not visible because the air in the bronchi are the same density as the rest of the air space in the lung)
  • Indicates an air-space disease/process, most commonly being pneumonia
16
Q

Pathology

A

Right Lung Atelectasis

  • Increased density over the entire lung (less air = increased density)
  • Mediastinum shift to the right
  • Right hemidiaphragm is significantly higher than the left
17
Q

Pathology

-What anatomic structure are the red arrows pointing to?

A

Right Upper Lung Atelectasis

-Arrows are pointing to the Horizontal (Minor) Fissure which will migrate to wherever the collaped lung is (in this case, it went superior)

18
Q

T/F Based on this X-ray, the abnormality is present and is therefore an “Aunt Minnie” for Bronchial Asthma

A

FALSE.

Bronchial Asthma is mainly a clinical finding with no significant associated radiology findings (NO AUNT MINNIE!!!!)

-Acute may show hyperinflation while chronic may appear normal or show interstitial pattern of lung disease
(non-specific)

19
Q

Pathology

-What radiographic appearance is present?

A

Bronchiectasis

-chronic irreversible dilation of bronchi (thick bronchial walls with altered lung volume)

Dx: Honeycomb appearance

20
Q

Pathology

-What condition may this mimic (and can be ruled out with if the costophrenic angles are normal)

A

Congenital Bronchogenic Cyst

-May mimic atelectasis, but since costophrenic angles are normal and the hemidiamphragm levels are normal, atelectasis is not likely.

21
Q

Pathology

A

Bronchopulmonary Sequestration

-Congenital malformation of the firegut causes a separate portion of lung from the bronchial tree

22
Q

Radiographic Sign

-What is the Dx?

A

Rabbit Ear Sign

-Dx: Bronchopulmonary sequestration

23
Q

Pathology

A

Emphysema

  • Bilateral/flat hemidiaphragm (or stair stepping appearance)
  • Overinflated lungs
  • Increased radiolucency
  • Prominent hilar vasculature
  • Increased retrosternal space (EARLIEST INDICATOR)
24
Q

Pathology

-What is the name of the area under the Arch of the Aorta that allows us to view the hilar vasculature

A

Emphysema

-Aortic Window

25
Q

Pathology

A

Bullous Emphysema

-big cyts like spaces secondary to emphysema

(Advanced form of Emphysema)

28
Q

Pathology

A

29
Q

Pathology

A

Pleural Effusion on the Right
