Fig. 2-173 A and B, A 6-year-old female Doberman Pinscher with a
3-day history of dyspnea with an acute onset. The dog’s heart rate
was rapid. There is a diffuse alveolar pattern infiltrate typified by
poorly defined and coalescent densities involving all lung lobes. A
few air bronchogram signs are present. The density is most severe in
the hilar area and radiates outward from that point. B, On the lateral
radiograph the trachea and tracheal bifurcation are elevated. The
main stem bronchi are split (arrows). Although the entire outline of
the cardiac silhouette cannot be seen, the tracheal alterations indicate
left-sided cardiomegaly. The radiographic changes suggest congestive
left heart failure. Diagnosis: Cardiomyopathy with congestive left
heart failure.
