Figure 30.23 A 13-year-old diabetic cat presented for chronic cough. On a computed tomographic study of the thorax (not shown),
air appeared within the mediastinum most likely due to an airway rupture. A single lateral thoracic image shows migration of the air
within the subcutaneous tissues, retroperitoneal space, pericardium, and mediastinum.

Figure 30.24 A 4-month-old DSH was hit by a car three weeks previously and had a compound fracture of the left tibia. On
presentation, she had a high white count and was febrile. (a) Lateral abdominal radiograph. (b) Ventrodorsal radiograph. There is a loss
of detail in the abdomen. In the caudodorsal abdomen, a soft tissue mass containing faint air opacity is seen on the lateral image
(arrows). (c) On abdominal ultrasound, a thick-walled structure with echogenic fluid center is noted. This structure appears to be in the
location of the medial iliac lymph node. An abscessed lymph node was found at surgery.
