Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Again seen is the small to moderate pneumothorax surrounding the right upper lobe , overall similar in configuration to the prior study . The densely opacified rind of right lung apex is now better aerated . Again seen are intra bronchial valves , right mid lung chain sutures , and a right - sided chest tube . Also again seen is the right perihilar opacity and triangular right infrahilar opacity as well as blunting of the right costophrenic angle . Background parenchymal and bullous changes noted . The mediastinum were remains relatively midline . On the left , the appearance is overall similar , with extensive apical bullous change and parenchymal opacities and probable slight superior hilar retraction . There is a focal irregular opacity measuring approximately ___ x 28 mm . Although this was less apparent on the prior CXR , it has a corresponding abnormality on the ___ chest CT . There is slight blunting of left costophrenic angle which appears new . Minimal atelectasis / scarring at the left lung base and no gross left pleural effusion .
    OUTPUT:
    
The right upper chest pneumothorax is overall similar , though the right lung apex parenchymal tissue is better aerated than it was on the prior study . Focal left midzone opacity is better seen than on the previous chest x-ray , but there is keeping with findings on the recent CT scan . Possible minimal blunting of the left costophrenic angle , without gross left effusion .
