Findings

The lung lobes are retracted from the thoracic wall and pleural fissure lines are visible. There is a marked peribronchial pattern in the entire lungs. There is a moderate alveolar pattern in the right caudal lung lobe. The cranial mediastinum is enlarged. The caudal portion of the trachea is narrowed. The cardiac silhouette is difficult to identify. The pulmonary vasculature is within normal limits.

Differential Diagnosis

Diffuse peribronchial and alveolar pattern throughout the lungs associated with pleural effusion and cranial mediastinal enlargement. These findings are suggestive of pulmonary parenchyma hemorrhage with pleural effusion and hemorrhage in the mediastinum. Other differentials should include bronchopneumonia, pulmonary neoplasia, or fungal disease. The appearance of the trachea may represent hemorrhage into the trachea or dynamic tracheal collapse. If clinically indicated, recheck radiographs are recommended to further monitor the process.

    Hi Alison, I have a question if you don’t mind: pyloric part of stomach is displaced cranially on lateral view.Does is always suggest decreased liver size?
    There is radiopaque material in gastric lumen on all xrays, is it clinically relevant?Could it be lead or other toxic material that didn t cause acute onset but chronic process that caused coagulopathy abnormalities due to liver failure?Thank you. Regards
    Anna

    I agree the deep chested conformation is causing some changes in the gastric position. However, the stomach is normally positioned on the other lateral and I can see liver beyond the costal arch, so the liver isn’t small. There is some gastric foreign material, and that is worth considering in this type of case. Zinc toxicity (from pennies) can cause anemia but not usually hemorrhage.
