    INPUT: A left - sided Port - A - Cath tip terminates at the lower SVC . The heart size is within normal limits . The mediastinal and hilar contours are normal . The lungs are clear of lobar consolidation with plate - like atelectasis or scarring along the major fissure than in the lower lateral lung zones bilaterally . Blunting of the right costophrenic angle likely represents a small - to - moderate pleural fluid versus thickening . There is no pneumothorax . There is no change from prior exams .
    OUTPUT:
    
No radiographic evidence of pneumonia ; probable small - to - moderate right pleural effusion versus thickening which is unchanged .
