This patient is a 67 year old female who had a chronic right pleural effusion.  A thoracentesis in March did not reveal a cause.  She presented in May to HH with a pain in her left chest and increased sputum production for 2 weeks. A CT scan was done.  What do you think was responsible for the air in the pleural space?
