title: Multiple rheumatoid nodules with rapid thin-walled cavity formation producing pneumothorax.
abstract: We report a rare case of multiple rheumatoid nodules that on chest CT demonstrated peripheral location with thin-walled cavity formation, rapid increase in size within several months, and complicating pneumothorax, pneumomediastinum, and subcutaneous emphysema due to bronchopleural fistula formation.
