Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Patient 's condition does not permit examination in upright position and AP frontal view with patient sitting in wheelchair was used with additional left lateral view . Comparison is made with two preceding chest examinations from ___ dated ___ . A wide - bore double - lumen catheter is present , apparently introduced via the right internal jugular approach and is seen to terminate in the lower SVC and right atrium apparently in unchanged location comparison with yesterday 's examination ( ___ ) . There is moderate elevation of the left - sided diaphragm and the lateral pleural sinus is blunted , indicative of some pleural reaction . When compared with the next preceding examination one day earlier , the diaphragmatic elevation is very similar in appearance . The previously identified local parenchymal density interpreted as representing an acute infiltrate has regressed and with the exception of some linear densities suggestive of some atelectasis in the left lower lobe area , no evidence of pulmonary parenchymal abnormalities can be identified . Observe that the diagnosis of an acute infiltrate was made on chest examination of ___ based on changes when comparing it with the previous chest examination of ___ . The new changes have regressed and indicate that they represented temporary fleeting process of the parenchyma superimposed on chronic elevation of the diaphragm , local pleural reaction and partial atelectasis in the left lower lobe . There is no evidence of pneumothorax .
    OUTPUT:
    
Stable chest findings . Chronic left lower lobe atelectasis , diaphragmatic elevation and mild blunting of the pleural spaces . If findings require therapy , must be decided on clinical manifestations .
