Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The cardiac silhouette is normal in size . The mediastinal contours are unremarkable . Mild prominence of the hila is noted . There are small bilateral pleural effusions . Diffuse increased interstitial markings likely reflects moderate pulmonary edema . Slightly more confluent opacities , especially in the right mid and lower lung are noted , which may represent a developing infectious process . Gaseous distention of small bowel loops in the upper abdomen is noted . Irregularity of the right anterolateral second rib may reflect prior fracture .
    OUTPUT:
    
Normal heart size but prominent hila and interstitial markings with small bilateral pleural effusions , likely reflecting moderate pulmonary edema . More confluent opacities in the right mid and lower lung may represent a superimposed infectious process .
