Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The cardiac silhouette size remains mildly enlarged . The mediastinal and hilar contours are unchanged with lymphadenopathy again noted . Enlargement of the pulmonary arteries likely reflects pulmonary arterial hypertension . Mild pulmonary vascular congestion persists . New patchy opacity in the right lung base could reflect an area of infection or atelectasis . Small bilateral pleural effusions may be present . There is no pneumothorax . No acute osseous abnormalities are detected .
    OUTPUT:
    
New patchy opacity in the right lung base could reflect an area of infection or atelectasis . Mild pulmonary vascular congestion and possible small bilateral pleural effusions . Mediastinal and hilar contours are unchanged compatible with known lymphadenopathy . Enlargement of the pulmonary arteries suggestive of underlying pulmonary hypertension .
