This week’s case is a 12-year-old female neutered Domestic long haired cat with episodes of coughing and weight loss for the last three months. This is a challenging pulmonary pattern. What do you think it is?
FindingsOn radiographs of the thorax, there is a diffuse, bronchointerstitial pattern with a nodular component. The lung lobes are rounded and retracted, with increased opacity in the pleural space. The cardiac silhouette is somewhat obscured but appears normal in size.
- Diffuse bronchointerstitial and nodular pattern may be caused by chronic lower airway disease, inflammatory disease, or neoplasia. The pleural component suggests effusion or soft tissue in the pleural space.
