Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: A PICC line terminates at the confluence of the brachiocephalic veins of the superior vena cava , and the patient is again status post tracheostomy . The heart appears enlarged . The mediastinal and hilar contours appear unchanged . There is a diffuse mild vascular prominence with indistinct vascular and interstitial markings suggesting mild congestion . Patchy retrocardiac opacity is minor and probably attributable to atelectasis . There is no definite pleural effusion although noting that the left costophrenic sulcus is partly excluded . There is no pneumothorax .
    OUTPUT:
    
Findings most suggestive of mild vascular congestion without definite pneumonia . Patchy retrocardiac opacity appears minor and may be associated with coinciding atelectasis . If concern for the possibility of pneumonia persists , however , then short - term followup radiographs could be considered , preferably with PA and lateral technique if feasible .
