Lung Entrapment Secondary to Loculated Rheumatoid Effusions Treated With Alteplase and Dornase.

Rheumatoid arthritis is a multisystemic inflammatory disease that can involve the respiratory system, including the pleural space. Most rheumatoid pleural effusions (PE) are incidentally found and do not require any treatment. Very rarely, however, they can become symptomatic and loculated, leading to lung entrapment or trapped lung.
