Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Patient rotation slightly limits assessment . A large right pleural effusion has increased in size compared to the most recent prior exam . There is associated right basilar atelectasis . The heart size is not enlarged . Mild pulmonary vascular congestion is likely present . Minimal streaky opacity in the left lung base likely reflects atelectasis . An abdominal drain is seen which terminates in the right upper quadrant , where there is relative lucency , new from the prior exam .
    OUTPUT:
    
1 . Increased right pleural effusion which is large in extent . Associated right basilar atelectasis . 2 . Probable mild pulmonary vascular congestion and minimal left basilar atelectasis . 3 . New lucency overlying the right upper quadrant , adjacent to an abdominal drain . Clinical correlation is recommended .
