Polycythemia in a llama.

PMID:  8050979     Owner:  NLM     Status:  MEDLINE    
The PCV of a llama increased from 50.8 to 74.0% during a 19-month period. The llama remained clinically normal unless stressed, when it would become dyspneic and tachypneic. Thoracic auscultation revealed sounds consistent with pneumonia, but were probably attributable to pulmonary congestion resulting from polycythemia. A diagnosis of secondary absolute polycythemia was made on the basis of high serum erythropoietin concentrations and no evidence of hypoxia. Necropsy revealed congestion of the lungs and liver. Cause of the polycythemia was not determined. Polycythemia should be considered as a differential diagnosis in a llama with exercise intolerance and harsh bronchovesicular sounds.
