Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: There is a large hiatal hernia . The heart is at least mild to moderately enlarged . The right upper mediastinal stripe appears lobular and prominent in width , but this does not represent a change . A tortuous enlarged aortic contour is also stable including calcification . There is probably a small pleural effusion on the left . Streaky opacities associated with the hernia are probably due to atelectasis . More generally , however , the pulmonary interstitium is prominent and hazy suggesting mild vascular congestion . The bones are probably demineralized to some extent .
    OUTPUT:
    
Findings suggesting mild vascular congestion . Suspected small pleural effusion on the left with patchy left basilar atelectasis . Cardiomegaly , but stable cardiac and mediastinal contours . Findings consistent with mild vascular congestion .
