Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The heart is mildly enlarged with a left ventricular configuration . A Port - A - Cath has been removed . The mediastinal and hilar contours appear unchanged . There is new moderate relative elevation of the right hemidiaphragm compared to the left side . There is a focal opacity projecting over the lateral right mid lung that is not specific but may correspond to the given history of lung cancer and which persists . In addition , there is superimposed widespread interstitial abnormality with upper zone redistribution of pulmonary vascularity including indistinctness , suggesting pulmonary vascular congestion . There is no definite pleural effusion or pneumothorax . Mild - to - moderate degenerative changes are noted along the thoracic spine .
    OUTPUT:
    
1 . Findings most consistent with mild - to - moderate pulmonary vascular congestion . 2 . Persistent focal opacity projecting over the lateral right mid lung for which differential considerations are broad but malignancy is a consideration given persistence and history . Correlation with outside imaging , if available , is recommended .
