    INPUT: Portable semi-upright radiograph of the chest demonstrates continued enlargement of the cardiac silhouette with areas of increased opacification involving the bilateral lung bases . Though the right basilar opacity has remained relatively stable since the prior examination , there has been progressive opacity at the left lung base . Though some of this may represent edema with atelectasis , underlying aspiration or pneumonia is not excluded . There are bilateral pleural effusions , unchanged since the prior examination .
    OUTPUT:
    
1 . Cardiomegaly and pulmonary edema with bilateral pleural effusions , largely similar to prior examination . 2 . Worsening left basilar opacity may be consistent with aspiration / pneumonia in the appropriate clinical context .
