Infant with respiratory distress

Normal inspiratory and expiratory CXR
Initial CXR AP (left) shows the heart to be enlarged and the pulmonary vascularity to be congested and there are low lung volumes. Repeat CXR AP obtained 5 minutes later in inspiration (right) shows the heart to be normal in size and the pulmonary vascularity is not congested and there are normal lung volumes.

The diagnosis was normal expiratory and inspiratory radiographs of the chest, with the expiratory radiograph mimicking cardiogenic pulmonary edema.
