    INPUT: PA and lateral views of the chest were provided . On the lateral view , there is area of increased opacity projecting posteriorly in the lower lung which may correspond with a subtle opacity in the right medial cardiophrenic recess on the frontal projection . While this finding was not definitely identified on the prior exam and therefore may represent a focal consolidation , though the possibility of a nodule is not excluded . Aside from this , there is no focal consolidation , effusion , pneumothorax . The heart size is stable and top normal in size . Mediastinal contour is unchanged with an unfolded thoracic aorta . The bony structures are intact . Multilevel degenerative changes with anterior osteophytes in the thoracic spine noted .
    OUTPUT:
    
Opacity in the posterior right medial lung base which was not clearly seen on prior exam and is somewhat atypical in appearance for pneumonia . Consider repeat chest radiograph post-treatment to ensure resolution or CT may be performed to further assess .
