Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Small left pleural effusion appears to have resolved . Perhaps minimal pulmonary vascular congestion . Otherwise , no significant change from the prior exam . There may be trace persistent right pleural effusion . Bilateral atelectasis persists . No focal consolidation , pneumothorax , or overt pulmonary edema . Stable prominent cardiomegaly . Stable calcification of the aortic arch . Stable mediastinal and hilar contours . Bilateral narrowing of the AC joint and high - riding humerus as well as heterotopic ossification superolateral to the right humeral head , suggesting chronic rotator cuff tear and severe osteoarthritis / post - trauma changes , are overall similar to prior shoulder radiographs .
    OUTPUT:
    
1 . Interval resolution of small left pleural effusion ; persistent probable trace right pleural effusion . 2 . Minimal pulmonary vascular congestion and bilateral atelectasis . 3 . No focal consolidation or frank pulmonary edema .
