    INPUT: Left PICC line terminates in the mid SVC . Multiple surgical clips project over the neck . The heart is mildly enlarged although obscured along its left border . Left basilar opacity likely reflects a combination of small pleural effusion and atelectasis . There are scattered interstitial opacities and architectural distortion suggesting some component of underlying interstitial process . Relative increased opacity at the right upper lung . The mediastinal and hilar contours are unremarkable . The aortic arch and descending thoracic aorta are heavily calcified .
    OUTPUT:
    
1 . Left basilar opacity likely combination of small pleural effusion and atelectasis , pneumonia not excluded . 2 . Interstitial abnormalities with probable component of chronic underlying interstitial process with possible superimposed acute infection in the right upper lung . 3 . Mild cardiomegaly .
