Today’s case is a 10 year old female neutered domestic short haired cat with dehydration, anorexia, and lethargy. Post your interpretations in the comments section.
The cardiac silhouette is enlarged, appearing tall on the lateral projection, and taking up more than 50% of the thoracic width on the d/v projection. There are diffuse interstitial to alveolar ventral pulmonary infiltrates concentrated in the accessory and cranial lung lobes. The colon is gas dilated.
Unclassified cardiomyopathy with cardiogenic pulmonary edema.
Cats in left heart failure often have a patchy alveolar pulmonary edema. It does not localize to the perihilar region as it does in dogs. Cats also often have pleural effusion, although this was not the case in this patient.
These images were taken several days after diuretic therapy was initiated. The pulmonary edema has resolved.
