    INPUT: Frontal and lateral radiographs of the chest demonstrate low lung volumes with resulting bronchovascular crowding . Increased opacities at the bilateral bases reflect small bilateral pleural effusions with adjacent atelectasis . There is cephalization of pulmonary vessels , indistinct hila bilaterally , and increased interstitial markings , consistent with pulmonary edema . Superimposed infection can not be excluded . There is no pneumothorax .
    OUTPUT:
