    INPUT: Right PICC tip terminates in the mid SVC . Heart size is mildly enlarged . The aorta is diffusely calcified . The mediastinal contour is unchanged , and there is no pulmonary vascular congestion . Small left pleural effusion appears slightly increased in size compared to the prior exam , and a trace right pleural effusion appears unchanged . Two peripheral nodular opacities within the left upper lobe appear similar , and the previously described right upper lobe nodule seen on chest CT is not clearly noted on the current exam . Left basilar compressive atelectasis is noted . There is scarring within the lung apices . Multiple clips are demonstrated within the midline upper abdomen . There are multilevel degenerative changes in the thoracic spine .
    OUTPUT:
    
1 . Slight interval increase in size of small left pleural effusion and unchanged trace right pleural effusion . Left basilar compressive atelectasis . 2 . Relatively unchanged appearance of 2 nodular opacities in left upper lobe , likely inflammatory or infectious in etiology . 3 . Previously noted right upper lobe pulmonary nodule seen on CT is not visualized on the current exam .
