Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Cardiac silhouette size remains mildly enlarged . The aortic knob is calcified . Mediastinal and hilar contours are unchanged . Rightward tracheal deviation at the thoracic inlet due to a left - sided masses compatible with known thyroid goiter , unchanged . Mild pulmonary vascular congestion and interstitial pulmonary edema appear slightly worse in the interval . Ill - defined perihilar opacities are are not substantially changed in the interval . Small bilateral pleural effusions are also similar in size . No pneumothorax is identified . Patient is status post right shoulder arthroplasty . Multiple remote bilateral rib fractures are re - demonstrated .
    OUTPUT:
    
1 . Mild pulmonary edema , slightly worse in the interval with persistent small bilateral pleural effusions . 2 . Perihilar ill - defined opacities bilaterally are unchanged . As noted previously , these could reflect multifocal pneumonia or be associated with underlying chronic rib fractures and continued imaging followup after treatment is again recommended .
