Thoracic radiograph: left lateral thoracic view of the skeletally immature alpaca cria demonstrating mild loss of the cranial waist, distention of the caudal vena cava, and a mild diffuse unstructured interstitial pattern in the lungs warranting cardiac evaluation. A reduced cervical tracheal diameter is also evident.
