6 year old DSH

September 11, 2020 By Allison Zwingenberger

This 6-year-old DSH cat was found laterally recumbent. What are your findings?

R LAT Thorax
DV Thorax
Show findings...

Findings

On image of the thorax, the cardiac silhouette is mildly enlarged and irregular in shape on the caudal border. The right caudal pulmonary vein is mildly tortuous. There are interstitial to alveolar infiltrates throughout the lung with focal concentration in the right caudal lung lobe and the left caudal lung lobe. The thorax is mildly hyperinflated. The kidneys are rounded and slightly small.

Differential Diagnosis

  • Pulmonary infiltrates and cardiomegaly most likely due to cardiomyopathy and heart failure. Other differentials include thromboembolic disease and pulmonary hemorrhage.
  • If cardiomyopathy is present, aortic thrombus may be the cause of lateral recumbency
  • Chronic renal disease

Diagnosis

Hypertrophic cardomyopathy, heart failure, and aortic thromboembolism.

Discussion

I have annotated the DV projection to highlight the mildly tortuous caudal pulmonary vein (see red arrows).
