Thorax

x-ray

There is a diffuse, patchy bronchointerstitial pattern throughout the lungs, with an increased focus in the left caudal lung lobe. The bronchial pattern is particularly visible on the lateral projections superimposed on the diaphragm and on the d/v projection.

There is also an increased soft tissue opacity in dorsal to the carina on the lateral projections, which is depressing the principal bronchi. This mass is displacing the principal bronchi laterally on the d/v projection and likely represents hilar lymphadenopathy.

Case Discussion

The pulmonary pattern and lymphadenopathy suggest an infectious inflammatory disorder such as fungal disease.

An endotracheal wash was performed which cultured Coccidiodes. Titers were also positive for coccidiodomycosis. The dog was treated with fluconazole and symptoms resolved over 9 months.
