This week’s case is a 7-year-old male neutered Domestic Shorthair cat with difficulty breathing. What are the two main findings?
FindingsThere is increased pharyngeal dilation with increased soft tissue opacity in the region of the larynx. The cervical and thoracic trachea appear small. The cardiac silhouette is markedly enlarged with a rounded appearance. Within the abdomen, the liver is poorly visualized. The stomach is gas distended and is located in close proximity to the diaphragm. There is poor definition of the ventral diaphragm and cardiac silhouette.
- Pericardial peritoneal diaphragmatic hernia. This is likely an incidental finding.
- Upper airway obstruction. Differential diagnoses include laryngeal neoplasia, edema, and inflammation.
