Pulmonary Patterns - Bronchial

Question 1

Summation of ____ and ____ on radiographs can limit usefulness

Answer 1

fluid
soft tissue

Question 2

What are the roentgen signs?

Answer 2

size
shape
margination
number
location
opacity

Question 3

On this thoracic radiograph, can we tell if the pericardium has fluid in it or not? Explain

Answer 3

We can tell it does NOT have fluid; otherwise, the fluid and soft tissue would summate

we can see the margins of the heart, so there is not fluid in the pericardium

in this case, it was a intrapericardial lipoma which made the actual heart bigger

Question 4

Label 1-4

Answer 4

1. tip of left cranial
2. left or right cranial lobe
3. right middle or caudal left cranial lobe
4. accessory lobe

Question 5

Label 5-11

Answer 5

5. right cranial lobe
6. right middle lobe
7. right caudal lobe
8. accessory lobe
9. left caudal lobe
10. left caudal part of cranial lobe
11. left cranial part of cranial lobe

Question 6

When you get thoracic radiographs, what questions should you start to ask yourself?

Answer 6

Question 7

What are the 3 pulmonary patterns?

Answer 7

1. bronchial
2. interstitial - unstructured and structured
3. alveolar

Question 8

What is a downside of pulmonary pattern recognition?

Answer 8

oversimplified, contrived, confusing terms
nonspecific

Question 9

What is the arrow pointing to? Normal or abnormal lungs?

Answer 9

thin bronchial walls

normal

Question 10

What is shown by the white dotted lines?

Answer 10

bronchi - normal airways

(side note but why would miss girl do arteries blue and veins red?)

Question 11

What does a bronchial pattern look like?

Answer 11

thick rings - lucency in the center

Question 12

What does this picture depict?

Answer 12

thickened bronchial walls

“tramtracks”

Question 14

What is this?

Answer 14

a marked bronchial pattern

Question 15

What is this?

Answer 15

a mild bronchial pattern

Question 16

How would you describe this?

Answer 16

a moderate bronchial pattern

Question 17

What causes bronchial patterns?

Answer 17

usually chronic inflammation
- hypertrophy of walls
- idiopathic fibrosis of walls

mineralization - chronic bronchitis (cats), hyperadrenocorticism, old dog lung

Question 18

How can bronchial patterns cause acute inflammation?

Answer 18

edema
smoke inhalation

Question 19

What does this show? What are causes of this, and what pulmonary pattern?

Answer 19

mineralization

• chronic bronchitis - cats
• hyperadrenocroticism
• “old dog lung”

Question 20

What else can lead to a bronchial pattern?

Answer 20

allergic airway disease

infection: bacterial, parasitic

diffuse neoplasia

atypical peribronchial cardiogenic edema

bronchial mineralization
