Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The cardiac silhouette is stably enlarged . The aorta is tortuous with calcification of the aortic narrowed . There is persistent dilatation of the left hemidiaphragm . No definite focal consolidation is identified . There is bibasilar scarring versus atelectasis . Mitral annular calcifications are noted . On the lateral view , density is seen in the region of the descending aorta , more prominent than on prior examination . This may represent fusiform dilatation of the descending aorta . Lucencies are noted in the region of the bilateral subcutaneous tissues , which may be related to overlying material . A possible fracture is seen of the left lateral fifth rib . Air-filled colon is seen in the left upper abdomen .
    OUTPUT:
    
1 . Possible left fifth rib fracture . Correlation with point tenderness is recommended . Please note that plain chest radiograph is inadequate to assess for traumatic injuries of the chest . If there is persistent concern , dedicated films of the ribs can be obtained for better evaluation . 2 . Possible aneurysmal dilatation of the descending aorta .
