Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: PA and lateral chest views were obtained with patient in upright position . Analysis is performed in direct comparison with the next preceding similar chest examination of ___ . Heart size is not enlarged . No configurational abnormality is present . The entire thoracic aorta is rather widened and elongated and shows advanced calcium deposits in the wall at the level of the arch . The pulmonary vasculature is not congested . However , there is a markedly irregular distribution of the peripheral pulmonary vasculature characterized by a local streaky scar densities and localized areas of increased translucencies . This finding in conjunction with the generally low positioned and flattened diaphragms is typical for COPD . Also noted is that the patient has a rather deep chest diameter as identified on the lateral view including an accentuated kyphotic curvature of the thoracic spine . In addition , one can identify multiple well - demarcated densities partially of calcium density most likely representing mediastinal nodes . When comparison is made with the next preceding chest examination of ___ , the described changes existed already at that time , thus findings are grossly stable . Comparison of the frontal views , however , identifies a small density in the left mid lung zone overlying the crossing between the posterior portion of the sixth left rib and that of the anterior portion of the fourth left ribs . This very small less than 0 .5 cm diameter density can not be identified on the old film and thus it is recommended to be followed up in a few weeks . Other most likely chronic changes have not undergone any significant alteration . There is no evidence of acute pleural effusion and no pneumothorax is seen in the apical area .
    OUTPUT:
    
Findings compatible with COPD . No acute parenchymal infiltrates or CHF . Small left lesion in mid lung zone recommended for followup examination .
