Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: AP single view of the chest has been obtained with patient in semi-upright position . Comparison is made with the next preceding PA and lateral chest examination of ___ . Heart size in comparison made on the frontal views has not significantly changed , thus cardiogenic pulmonary edema is unlikely . There are new bilateral hazy densities on the lung bases , more marked on the left side where the diaphragmatic contour is completely obliterated . This is related to a pleural effusion which also blunts the lateral pleural sinus . The right - sided pleural sinus remains free , but the hazy density is similar to that on the left side , probably represents smaller amount of pleural effusion layering in the posterior compartment of the pleural space with the patient in recumbent position . There is no evidence of new acute parenchymal infiltrates , and the pulmonary vasculature does not show any congestive pattern .
    OUTPUT:
    
Development of pleural effusions as identified on portable examination . Better quantification of amount could be accomplished by a lateral view .
