    INPUT: Heart size is normal . Mediastinal contours are unchanged . Mild enlargement of the hila bilaterally is compatible with underlying lymphadenopathy , as seen on the prior CT . Pulmonary vasculature is not engorged . Traction bronchiectasis and increased interstitial opacities in both lung apices and bases do not appear substantially changed in the interval and likely reflect chronic findings . No new focal consolidation , pleural effusion or pneumothorax is visualized .
    OUTPUT:
    
Chronic appearing opacities in both bases along with bilateral hilar lymphadenopathy , compatible with history of sarcoidosis . No new focal consolidation identified .
