Today’s case is a 2-year-old male neutered Spaniel mix adopted from Mexico with intermittent right thoracic and left pelvic limb lameness, mild fever, and increased respiratory rate. What are your findings?
There is a diffuse miliary nodular pattern in the pulmonary parenchyma. The cardiac silhouette and pulmonary vasculature is normal. There is mildly increased opacity dorsal to the carina in the region of the tracheobronchial lymph nodes. No abnormalities are noted in the remainder of the mediastinum or pleural space. There is stippled irregular periosteal reaction and multifocal lysis of the wing and spine of the scapula seen on the lateral projections.
The miliary pulmonary nodules, tracheobronchial lymphadenopathy, and polyostotic aggressive bone lesions are most consistent with fungal disease.
