Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The patient is slightly rotated . Allowing for this , the heart is not enlarged . The aorta is calcified , but the cardiomediastinal contours are otherwise within normal limits . Calcified coronary arteries are noted . Rounded density at the right lung base and at the periphery of the left base is thought to represent nipple shadows . Crowding of vessels noted in the right base inferiorly . No increased interstitial markings seen in this area on the ___ radiographs . There is artifact overlying posterior chest on the lateral view . While a focal infiltrate there can not be excluded , there are no corroborating findings on the AP view . Otherwise , no focal consolidation , pleural effusion or pneumothorax . Chain sutures are noted at the right lung apex for which clinical correlation is requested . Focal vascular calcifications are seen in the left upper arm . Density of the bilateral humeral heads may reflect bone infarcts .
    OUTPUT:
    
Limited assessment of the posterior chest due to overlying artifact . Allowing for this , no pneumonia identified . If clinically indicated , a repeat lateral view could be attempted at no additional charge to the patient . Mild prominence of vessels at the right lung base medially is thought to represent artifact due to rotation . Differential includes atelectasis and bronchiectasis . The appearance is less pronounced than on radiographs from ___ and ___ . Chain sutures noted at the right lung apex , compatible with prior surgery . Aortic and coronary artery calcification noted . Vascular calcifications also seen adjacent to the distal humerus . Suspected bilateral humeral head osteonecrosis .
