Right lateral thorax
Left lateral thorax
The caudal thoracic oesophagus is moderately dilated (teal arrows) and contains a large oblong soft tissue opacity (orange arrows) that contains formed margins. This soft tissue oesophageal luminal focus is causing marked compression of the carina and mainstem bronchi (pink arrow). The cardiovascular structures and cranial mediastinum are normal. On a VD, a focal mild alveolar pattern is present within the right cranial lung lobe (red arrows) however, this is not seen on the other VD or the left lateral. The thoracic spine, ribs and visible abdomen are normal.
1. Thoracic oesophageal foreign body that is causing marked compression of the carina and mainstem bronchi.
2. Focal right cranial lung lobe pulmonary atelectasis.
The oesophageal foreign body is the cause of the clinical signs. Oesophagoscopy is recommended at this time.
