Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Left lateral and basilar calcified pleural plaque is redemonstrated , which limits assessment of the underlying lung parenchyma . There is a large hiatal hernia redemonstrated , and this obscures the size of the cardiac silhouette , which is likely mildly enlarged . The aortic knob is calcified . There is no pulmonary vascular congestion . Since the prior study , there is a new right basilar opacity which llikely reflects a combination of a moderate pleural effusion and atelectasis , though infection or aspiration is not excluded . Patchy opacity in left lung base may also be present , but again this area is not well assessed given the presence of overlying pleural plaques . There is biapical pleural thickening and scarring . Old rib deformities are noted bilaterally . There is no pneumothorax .
    OUTPUT:
    
New opacity within the right lung base which likely represents a combination of a moderate sized pleural effusion with associated atelectasis though infection or aspiration can not be excluded . Calcified pleural plaque in the left lung base somewhat limits evaluation of the underlying lung parenchyma , and a left basilar process can not be completely excluded . Large hiatal hernia .
