Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Right Port -A - Cath is again noted . Streaky right middle lobe opacity is likely in part due to atelectasis . Bulky right hilar and mediastinal adenopathy was better seen by prior cross - sectional imaging . There is however new retrocardiac opacity which is only clearly seen on the frontal view . A left apical opacity is again seen and could be due to prior radiation . There is no effusion . Surgical clips again project over the left axilla .
    OUTPUT:
    
Left basilar opacity seen only on the frontal view could be due to atelectasis although infection is not entirely excluded . Otherwise , no significant interval change including streaky right middle lobe opacity and mediastinal / hilar adenopathy .
