2010 Image Interpretation Session - Case 4

Signalment: 3-year-old, male castrated, German Shepherd mix

History: presented to Emergency Service for a 4 day history of a hacking cough. He was diagnosed with Bordatella and pnuemonia when he was 8 weeks old and treated at that time. Since then, he has always had a chronic increased respiratory effort. Over the past 2 months, he has been on an Albuterol inhaler (2 puffs a day) with 10mg of Prednisone every 3-4 days. This regimen seems to have bettered clinical signs to some degree. However, in mid-December, he presented to ER for acute respiratory distress. After receiving oxygen, his condition improved.

Clinical Findings: T=104.1*F (resolved after resp distress resolved); P=130bpm; R=pant; Weight 23.4kg; BCS 4/9. He was bright, alert, and responsive. His mucous membranes were pink and moist with a CRT <2 seconds. Palpable peripheral lymph nodes were within normal limits. Heart beat was strong and synchronous with femoral pulses. Crackles could be heard in lung fields most notably in the ventral regions. Abdominal palpation was within normal limits and did not elicit a painful response. He did not ambulate with lameness or ataxia. His hair coat has a mild degree of thinning. On the way to the scale in the hallway, he got anxious and began breathing heavily with forced expiratory effort accompanied intermittently with an audible wheezing sound.

Images provided: 3 radiographs and 11 CT images of the thorax
