Thoracic radiography is often one of the first diagnostic tests performed when pulmonary or cardiac disease is suspected in alpaca crias. Thoracic diseases are relatively common in camelid crias and include pneumonia, congenital heart malformations, and pathological changes related to trauma.1,2 Correct interpretation of test results requires a thorough understanding of anatomy and variations in morphology or organ visibility unique to this species and age of patient. Although the thoracic radiographic appearance of many clinically normal animals, including adult llamas, has been described, little information is available for alpaca crias. The purpose of the study reported here was to quantitatively and qualitatively assess the radiographic appearance of the thorax of clinically normal alpaca crias.
