Please review Maurie's clinical history.
Location of images: Thoracic radiographs obtained.
Views of images: Left lateral view and dorsoventral (DV) views.
Technical issues: Both views have good positioning and good exposure.
Cardiac size including VHS: The cardiac silhouette is obscured by moderate to severe pleural effusion. Vertebral heart scale cannot be calculated, but the heart appears to be enlarged, especially on the lateral view.
Other Findings: The lung lobes are partially retracted and appear to be rounded, which may be an indication of pleural fibrosis.
|Radiographic Interpretation:||Severe pleural effusion with evidence of chronicity. Probable congestive heart failure.|
|Discussion:||The orgin of pleural effusion can be challenging to identify based on thoracic radiographs alone. Cardiac size and shape, as well as pulmonary vessels, may be obscured by the effusion. Other differential diagnoses for this type of appearance on thoracic radiographs includeds chylothorax, pyothorax, or neoplastic effusions. In this cat, the presence of distended jugular veins on physical examination supports a cardiac origin for the effusion (i.e. congestive heart failure).|
|Treatment/Management:||After thoracocentesis and stabilization, echocardiographic examination revealed restrictive cardiomyopathy. The rounded appearance of the lung lobes may reflect pleural fibrosis, and in this cat, likely indicates that the onset of effusion was more chronic than it appeared based on clinical signs. The cat responded well to chronic therapy with furosemide, benazepril and pimobendan.|
