Imaging Evaluation of Dogs and Cats with Dysphagia
Figure 1
(a) A right lateral thoracic radiograph depicts a 1-year-old spayed female Yorkshire terrier with an acute onset of retching and regurgitation. A rawhide foreign body is present in the cranial thoracic esophagus (black arrows). Notice that the foreign body is difficult to see because raw hide is soft tissue density but a gas bubble in the middle is visible (*). The distended esophagus is pushing the trachea ventrally (white arrow). There is a small amount of air in the esophagus oral to the obstruction. (b) A dorsoventral radiograph of the same dog as in (a) shows widening of the esophagus in the location of the foreign body (white arrows).
