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 study of ___ . The postoperative apical density interpreted as postoperative loculated pneumothorax now filled in with pleural scar appears grossly unchanged . No remaining cavity with fluid level can be seen . The previously identified marked prominence of the right hilar area persists . It is now noted that a parenchymal density in the lateral area of the right upper lobe has become more prominent and coincides with the local pleural density that has developed along the lateral axillary chest wall . Comparison of the lateral views confirms this suspicion as the posteriorly oriented density overlying the superior vertebral bodies has clearly increased . Right - sided pleural densities are unchanged without development of new free fluid . The left hemithorax remains unchanged and normal .
    OUTPUT:
    
Follow up with two weeks examination interval indicates scar formations in apical area , persistent unchanged prominence of hilar changes , but now occurrence of increasing parenchymal density occupying the lateral posterior area , coinciding with local pleural density . The latter finding is worrisome as it is not compatible with normal regression of postoperative changes . Referring physician , ___ was paged at 3 :40 p .m . so to transmit expressed concerns .
