    INPUT: Frontal and lateral views of the chest were obtained . Blunting of the left costophrenic angle is consistent with a moderate pleural effusion with overlying atelectasis . Small right pleural effusion is difficult to exclude . There is mild - to - moderate interstitial pulmonary edema . The cardiac silhouette is mildly enlarged . The aorta is calcified . A left - sided PICC is again seen , distal aspect not well appreciated ; however , seen to at least the level of the low SVC . Left base opacity may be due to combination of pleural effusion and atelectasis ; however , underlying consolidation is not excluded .
    OUTPUT:
