    INPUT: Lung volumes are low . Midline sternotomy wires are well aligned . Right sided PICC now terminates in right axilla . The cardiac silhouette and pulmonary vasculature unremarkable . Again noted is right paratracheal soft tissue , consistent with known lymphadenopathy . Diffuse , patchy , right - sided opacity is progressed since the most recent examination . Left basilar opacity is more prominent as well . No definite pleural effusion or pneumothorax .
    OUTPUT:
    
Heterogeneous opacities throughout the right lung and left lung base have worsened . Given waxing and waning over serial radiographs , there is concern for recurrent aspiration / aspiration pneumonia .
