Small Animal Radiology and Ultrasound: A Diagnostic Atlas and Text

188 Small Animal Radiolo g y and Ultrasono graphy
Fig. 2-168 A and B, A 7-year-old
female mixed breed dog was brought
for evaluation of a productive cough
that had persisted for 7 months following
exposure to smoke. There are
focal areas of pulmonary density in
the left caudal and right cranial lung
lobes (arrows). There is a diffuse
increase in pulmonary bronchial and
interstitial densities. The diffuse pulmonary
density is secondary to the
smoke inhalation and represents
interstitial fibrosis. The focal areas of
density (patchy alveolar pattern
infiltrates) are most likely due to secondary
bacterial infection.
Diagnosis: Bacterial pneumonia secondary
to chronic interstitial and
bronchial fibrosis due to smoke
inhalation.
