Today’s case is a 9 year old domestic short haired cat with a 1-year history of episodic, non-productive coughing.
There is a mixed, bronchointerstitial pattern throughout the lungs. “Donuts” are visible on the v/d projection overlying the diaphragm.
Inflammatory airway disease
Bronchoscopy revealed mucus plugging of small airways and evidence of inflammation. The bronchial lavage was also inflammatory in nature. These mild bronchial infiltrates are characteristic of inflammatory airway disease in cats. In this case, fibers found in the lavage fluid were similar to those in the natural kitty litter the owner was using, which may have caused a foreign body reaction.

I feel like I need a new monitor and a magnifier. Do I have to sell my car to buy a new monitor? Kidding. The images (especially pulmonary images) are kinda fuzzy on my screen, although I’m able to notice some donuts on VD view. I think my eyes and brain need to be trained again under supervision of radiologists.

I know, cat thoraxes are difficult to interpret! There is also some loss of spatial resolution in digital images even though the contrast is much better. Try the “original size” button and magnify the image. Also, compare it to a normal cat’s thorax to see the difference (overall lung opacity, donuts).

This one was really challenging. Thanks doctor!

Are the caudal pulmonary aa enlarged too? On VD they look like it. My eyes are crossing though.
