Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Single frontal view of the chest demonstrates tracheostomy in standard position and intact median sternotomy wires . Multiple surgical clips in the right upper lung base compatible with history of right upper lobectomy for squamous cell carcinoma . Configuration of near complete opacification of the right lung with a large pleural effusion and elements of loculation in the right upper lobe and in subpulmonic location appears similar as compared to one day prior , with a small area of somewhat better aerated lung in the mid right hemithorax . The left lung is better aerated , with persistent left basilar atelectasis and small effusion . There is no discernable pneumothorax . Cardiomediastinal silhouette is within normal limits allowing for semi-upright positioning and AP technique . There is evidence of posterior thoracotomy with disruption of posterior ribs .
    OUTPUT:
    
Slightly better aeration of the compressed right lung . Similar large loculated right pleural effusion .
