Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Left PICC ends in the proximal to mid SVC . Median sternotomy wires are present . Moderate cardiomegaly , mildly increased from prior . Interstitial edema persists , similar to prior . There is blunting of the left costophrenic angle , consistent with a left - sided pleural effusion . Retrocardiac opacity likely represents atelectasis . A rounded density in the left upper lobe likely corresponds to mass seen on prior CT scan . There is no pneumothorax .
    OUTPUT:
    
1 . Left PICC ends in the proximal to mid SVC . 2 . Persistent cardiomegaly and left pleural effusion . 3 . Interstitial edema . 4 . Redemonstrated left apical mass like opacity corresponding to lesion seen in this location on prior CT scan .
