Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Two portable views of the chest . There is a moderate - to - large right - sided pneumothorax . Surgical chain sutures seen in the left paramediastinal location compatible with prior resection . Assessment for possible mediastinal shift is limited given lack of priors available and probable underlying volume loss on the left due to prior resection and rotation of the patient to the right . It would be difficult to exclude degree of mediastinal shift . Linear opacity at the lung bases , suggesting atelectasis . Cardiomediastinal silhouette is otherwise grossly unremarkable . No acute osseous abnormality is identified .
    OUTPUT:
    
Moderate - to - large right - sided pneumothorax . Evaluation for signs of mediastinal shift , limited as detailed above . Finding of pneumothorax was known to the team discussed by Dr . ___ ___ after study was performed . Evaluation of possible mediastinal shift was discussed with Dr . ___ by Dr . ___ at approximately 3 :45 p .m . on ___ .
