Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The heart is again markedly enlarged . The left lung base is opacified , which is difficult to assess in greater detail , but may reflect pleural effusion , possibly with atelectasis or even pneumonia . There is probably at least a trace pleural effusion on the right . There is increased perihilar fullness bilaterally suggesting mild vascular congestion . A new opacity in the right lower lung is relatively focal and potentially indicates pneumonia . An atypical distribution of pulmonary edema could also be considered , however . Moderate rightward spinal curvature is centered along the lower thoracic spine .
    OUTPUT:
    
New patchy basilar opacities in addition to suspected pulmonary congestion , at least mild . Whether the latter may also potentially explain right basilar opacity is uncertain , and developing pneumonia or an atypical distribution of edema could be considered .
