Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Low lung volumes with right base atelectasis versus developing pneumonia . Small bilateral pleural effusions . Cholecystectomy clips . Calcified thoracic aorta . Heart size within normal . No pneumothorax . Mild interstitial prominence is noted . An ovoid focus overlying the right chest on frontal view measures 12 mm .
    OUTPUT:
    
Bilateral interstitial prominence , nonspecific finding , possibly indicating interstitial lung disease rather than interstitial edema . CT correlation would be helpful for characterization . Ovoid focus in the right chest , possible pulmonary nodule . Recommed comparison with prior studies and acquisition of CT if clinically warranted . Small bilateral pleural effusions .
