Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The heart is moderately enlarged . There is vague suggestion of a possible air - fluid level projecting over the lower central mediastinum so potentially there is a substantial hiatal hernia although uncertain . The pulmonary interstitium is slightly prominent , suggesting a component of pulmonary venous hypertension or slight fluid overload including thickening of the minor fissure . A very small pleural effusion is suspected , at least on the right side . In addition there are patchy basilar opacities that in the clinical context and with low lung volumes , likely reflect minor atelectasis . The bones appear demineralized .
    OUTPUT:
    
Findings suggesting slight fluid overload or pulmonary venous hypertension including cardiomegaly and a small suspected right - sided pleural effusion which is suspected . Patchy opacities most suggestive of minor atelectasis . Findings which may suggest a hiatal hernia .
