    INPUT: The cardiomediastinal silhouette and pulmonary vasculature are normal . There is no pleural effusion or pneumothorax . The linear opacities seen in the right base likely represent atelectasis . No definite consolidation is identified . Given density of breasts , however , evaluation of lung bases is limited .
    OUTPUT:
    
No acute intrathoracic abnormality . If there is persistent concern for pneumonia , conventional PA and lateral radiographs can be obtained for better evaluation of the lung bases , suboptimally assessed on this single portable projection in the setting of dense overlying breast tissue .
