Figure 19.8 Lateral (a) and ventrodorsal (b) thoracic images of a cat presented for regurgitation. A large soft tissue mass with some
lucent areas is noted in the caudodorsal thorax (lateral view) and superimposed over the cranial abdomen (arrow) on the ventrodorsal
view. The stomach is not visualized on either view. A hiatal hernia was diagnosed on fluoroscopy, after oral administration of barium
contrast.

Figure 19.9 Left lateral (a), right lateral (b), and ventrodorsal (c) thoracic images of a cat presented for vomiting. On the left lateral
view (a), the esophagus is moderately dilated. A poorly defined soft tissue opacity is noted in the caudodorsal lung field (arrow). On the
right lateral image (b), the caudodorsal mass is much better visualized, and contains a small amount of air. The stomach is not
visualized caudal to the diaphragm. The stomach appears to be in a normal position on the (oblique) ventrodorsal view (c), and no
mass is visualized. A hiatal hernia was diagnosed based on the radiographs, but appeared to be intermittent. The thorax films were
normal 24 hours later.
