Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Frontal and lateral views of the chest were obtained . Right - sided PICC is again seen , terminating in the right atrium . There are low lung volumes . Bilateral calcified pleural plaques are again seen . Additional perihilar opacities are seen , left greater than right , raising concern for underlying pulmonary edema which may be asymmetric . Underlying infection is not excluded , particularly in the left lung . Patchy left base opacity may relate to prominent vascular structures and / or atelectasis , although underlying infection is not excluded . No large pleural effusion is seen . There is no evidence of pneumothorax .
    OUTPUT:
    
Opacities projecting over the bilateral lung fields , in part relating to calcified pleural plaques , although increased perihilar opacities compared to the prior study , left greater than right , raise concern for pulmonary edema with possible underlying infection , as above .
