Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Cardiac silhouette size is difficult to assess given the presence of a moderate left pleural effusion which appears increased in size compared to the previous chest radiograph . Left hilar and infrahilar masses as well as the left upper lobe mass are grossly unchanged compared to the recent chest CT . Left basilar opacity may reflect compressive atelectasis but infection is difficult to exclude . Chain sutures within the right upper lobe are re - demonstrated . The aorta is tortuous . Pulmonary vasculature is not engorged . No pneumothorax or right - sided pleural effusion is demonstrated . There are no acute osseous abnormalities .
    OUTPUT:
    
Increased size of left pleural effusion , now moderate , with left basilar opacity which may reflect compressive atelectasis . Infection within the left lung base can not be completely excluded . Grossly unchanged appearance of left upper lobe , left hilar and left infrahilar masses compared to the previous CT .
