Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: PA and lateral chest views were obtained with patient in upright position . Comparison is made with the next preceding similar chest examinations of ___ and ___ . Size and appearance of thoracic aorta unchanged . The previously described right - sided apical pleural density remains unaltered . The on next previous examination suspected remaining parenchymal densities and pleural thickening in the axillary area has regressed in size , appears to blend the apical pleural scar formations . Post-operative appearance of progressive right - sided hilar stump has not increased in prominence . No new parenchymal infiltrates in the remaining right - sided lung tissue which demonstrates a basal pleural scar formation at the diaphragmatic surface and no new parenchymal infiltrates or masses . Left hemithorax remains unchanged and within normal limits .
    OUTPUT:
    
The presently identified latest interval changes are compatible with increased pleural scar formations . Thus , there is no conclusive evidence for reoccurrence of pulmonary malignancy . Considering the rather large pleural scar formations , further followup with monthly intervals is recommended .
