Streaky left retrocardiac opacity most likely represents atelectasis . No pleural effusion or pneumothorax . Intrathoracic lymphadenopathy , a right juxta hilar mass , and postobstructive changes in the right middle and lower lobes have substantially improved compared to ___ radiograph with some residual patchy and linear atelectasis as well as bronchial wall thickening . These findings are more fully evaluated on the concurrent CTA .
    OUTPUT:
    
No acute cardiopulmonary process . 1 . See full report of concurrent CTA for complete description of patient 's findings related to intrathoracic malignancy .
