    INPUT: There are relatively low lung volumes . Numerous patchy nodular opacities seen in the lung fields bilaterally most likely relate to patient 's known metastatic disease . More confluent patchy opacities in the left mid to lower lung could be due to areas of focal consolidation from infection or pulmonary contusion in the setting of trauma . No pleural effusion or pneumothorax is seen . The cardiac and mediastinal silhouettes are unremarkable . No obvious displaced rib fracture seen although the study has low sensitivity for the detection of such .
