Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: PA and lateral chest views have been obtained with patient in upright position . Comparison is made with the next preceding single view AP projection chest examination of ___ . The on previous examination identified linear and partially calcified scattered abnormalities in both apical portions remain completely unchanged as can be identified by ordinary radiography . Thus , they most likely represent fibrotic and calcified scars after old and now inactive specific infection . No new parenchymal abnormalities identified . The lateral pleural sinuses are free . As apparently followed our previous recommendations , lateral views were obtained and the integrity of both posterior pleural sinuses appears preserved . Thus , there is no evidence of any acute pleural effusion in the pleural spaces .
    OUTPUT:
    
Stable bilateral apical scar formations , compatible with old specific infection clearly stable during latest examination intervals .
