There is retraction of the lung lobes from the parietal pleura and fluid within the pleural space. There are multiple pleural fissure lines between lung lobes. There is border effacement of the cardiac silhouette and ventral aspect of the diaphragm. There is a diffuse increased opacity throughout the lung lobes. There is gas within the pleural space at the caudal dorsal thorax on the lateral view. There is dorsal deviation of the intrathoracic trachea. In the limited view of the abdomen, there is cranial displacement of the gastric axis and the ventral liver margin is not visible. There is a 3.8 cm metal opaque spherical structure within the plane of the pylorus on the lateral view. At the caudoventral thorax, there are multiple indistinct mottled soft tissue and gas opacities. There is decreased abdominal serosal detail within the cranial abdomen.
Findings are most consistent with a diaphragmatic hernia. Suspect herniation of the small intestines and liver. Pleural effusion with differentials including hemorrhage, modified transudate, and lesser consideration given to chyle and exudates. Small volume pneumothorax. Increased opacity within the lungs is most consistent with superimposition of pleural effusion and atelectasis. Pyloric foreign body. Decreased abdominal serosal detail may be consistent with a thin patient, however cannot entirely rule out peritoneal effusion.
