    INPUT: The lungs are well - expanded . The opacity in the region of the left upper hemithorax is increased in size from the prior exam . No focal consolidation to suggest pneumonia . No pleural effusion , pneumothorax , or pulmonary edema . The cardiomediastinal silhouette is unchanged . Stable tortuosity of thoracic aorta . The leftward deviation of the trachea with associated narrowing of the lumen appears stable and is consistent with a thyroid goiter . Stable appearance of the hila .
    OUTPUT:
    
1 . No acute cardiopulmonary process . 2 . Interval increase in the left upper hemithorax opacity , which may be intraparenchymal or a pleural plaque .
