Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: AP right frontal and lateral views of the chest provided . Midline sternotomy wires and mediastinal clips are noted . The patient is rotated to the left , which somewhat limits evaluation , and on the lateral view , the patient 's arm obscures the visualization through the chest . There is blunting of the left CP angle which on prior CT is likely reflective of left basal pleural thickening . The possibility of a superimposed small effusion is difficult to exclude . The right lung remains clear . The imaged portion of the left upper lung is clear . Patient 's rotation limits the evaluation of the cardiomediastinal silhouette . The bony structures appear grossly intact .
    OUTPUT:
    
Mild blunting of the left CP angle is likely reflective of pleural thickening and possible small effusion . Otherwise , unremarkable , though evaluation is markedly limited as stated above .
