lungs appear well inflated without evidence of focal airspace consolidation, pleural effusions, pneumothorax, or pulmonary edema. there is a <num>-<num> mm pulmonary opacity in the periphery of the right mid lung overlying the superior edge of the sixth posterolateral rib. comparison to old films would be helpful to assess for stability. if unavailable, further imaging with dedicated chest ct should be considered. heart is upper limits of normal in size given portable technique. mediastinal contours are within normal limits. no acute bony abnormality is appreciated.
