    INPUT: PA and lateral chest views were obtained with patient in upright position . The heart size is within normal limits . No configurational abnormality is identified . Unremarkable appearance of thoracic aorta and no mediastinal masses are seen . Pulmonary vasculature is not congested . The lateral and posterior pleural sinuses are free from any fluid accumulation , and no pneumothorax is identified in the apical area . On the right lung base confirmed on the lateral view in posterior right lower lobe area , there exist a few small scattered parenchymal patchy densities which are indicative of some acute inflammatory peribronchial processes . When comparison is made with the next previous available PA and lateral chest examination of ___ , these subtle parenchymal densities are clearly new as they did not exist on the previous study . Similar as on the previous examination , the diaphragms are rather low positioned and appear flattened , a finding consistent with COPD . There are no other for lung tumor suspicious findings on this routine PA and lateral chest examination in this apparent heavy smoker .
    OUTPUT:
    
Right - sided basal posterior scattered infiltrates indicative of bronchopneumonic processes . Followup examination in about two to three weeks after treatment is recommended .
