Today’s case is a 5-year-old male neutered domestic shorthaired cat with vomiting and anorexia. Transferred from referral hospital after no response to fluid therapy. What are your findings?
There is a large, broad based soft tissue and gas opacity in the caudal mediastinum. The thoracic esophagus contains some gas cranial to this structure. The stomach is markedly distended with fluid. There is a small amount of pleural effusion causing increased opacity ventral to the cardiac silhouette and widened pleural fissure lines. The cardiovascular structures are normal.
Hiatal hernia with gastric obstruction or ileus. The gas in the esophagus may indicate esophagitis. Pleural effusion may be secondary to esophageal changes however fluid overload is also possible.
A 4 cm hiatal hernia was reduced at surgery. 75% of the stomach was located in the caudal mediastinum. A gastropexy and esophagopexy were also performed.
An echocardiogram was normal. The cause of the pleural effusion was not determined.
Recovery was uneventful.
