Question 5

What are causes for a bronchial pattern?

Answer 5

Allergic airway disease, infection, chronic inflammation, cardiogenic pulmonary edema, diffuse tumor.

Question 6

What are possible consequences of chronic bronchial disease?

Answer 6

Lobar collapse, bronchiectasis, spontaneous rib fractures, pulmonary hyperinflation and bronchial mineralization.

Question 7

Lobar collapse is often seen in cats with what condition? which is the most commonly associated lung lobe?

Answer 7

Lobar collapse is most often associated with cats with asthma. The right middle lung lobe is most affected.
