Dense vascular calcifications are noted in the upper abdomen .
    OUTPUT:
    
Mild pulmonary vascular engorgement with small bilateral pleural effusions . Patchy opacities in the lung bases likely reflect atelectasis though infection is not excluded in the right lung base in the correct clinical setting .
