Findings

The cardiac silhouette is markedly enlarged on all projections. There is a bulge in the region of the carina and at the base of the right middle lung lobe, which is increased in opacity. The pulmonary vasculature is enlarged. There is a diffuse bronchointerstitial pattern throughout the lungs, and there is increased opacity in the region of the left cranial lung lobe.

Differential Diagnosis

Cardiomegaly is most likely caused by cardiomyopathy due to primary heart disease or hyperthyroidism. The mass effect in the right cranial thorax may be a pulmonary mass with secondary right middle lobe atelectasis or an enlarged cardiac chamber. The diffuse bronchointerstitial pattern is consistent with lower airway disease, which may have infectious and noninfectious inflammatory components. The opacity in the left cranial thorax may be due to effusion or a cranial thoracic mass.

Diagnosis

  • Hypertrophic cardiomyopathy
  • Hyperthyroidism
  • Ruled out thoracic mass by ultrasound examination – enlarged atrium
  • No abnormalities in left cranial thorax

    On right lateral projection is very visible a bulge on the dorsal aspect of the hear, probably enlarged left atrium, or less likely hilar linfonode. On both lateral projections vena cava is enlarged, as well as general pulmonary vasculature and cardiac silhouette. On DV and VD projections there is a valentine shaped heart. According to history and age, I would assume severe cardiac failure, with cardiomegaly, though rare in cats.
