Figure 4.5.4 Barotrauma (Canine) CT
Adult dog with immune‐mediated mega­
esophagus and pneumonia. There is a uniform
cuff of perivascular gas surrounding the pul­
monary arteries. (a,b: arrowheads). The dog
had been under positive‐pressure ventilation
while under anesthesia, which was thought to
have caused alveolar or small airway rupture
leading to the perivascular gas dissection.
