3. Fig. 2
Thoracic radiograph of neonatal foal with viral pneumonia. Note alveolar pattern distributed throughout entire lung field with prominent air bronchograms. This pattern can also be seen with acute respiratory distress syndrome after overwhelming sepsis and in the surfactant deficiency seen in extremely premature foals, usually those less than 280 days' gestation.
