    INPUT: Subtle nodular opacities projecting over the bilateral upper lung , along the anterior right second rib and on the left between the anterior left second - third ribs spaces are nonspecific . No prior study available for comparison . There is also subtle nodular opacity at the left lung base which could relate to atelectasis . No discrete focal consolidation is seen . No pleural effusion or pneumothorax is seen . The cardiac and mediastinal silhouettes are unremarkable . No radiographic evidence of hilar or mediastinal lymphadenopathy .
    OUTPUT:
    
Subtle nodular opacity projecting over the left upper and lower lobes as well as possibly over the right upper lung are nonspecific and not well assessed on this study .
