A pleuroscopy is a medical procedure in which doctors can examine the pleural cavity, the space between the 2 layers of tissue(the pleura) that line the lungs.
During a pleuroscopy, a tube called a pleuroscope is inserted into the pleural cavity through a small incision in the chest wall. Doctors can then visualize the pleural cavity with a special camera. A pleuroscopy can be a relatively noninvasive way to inject medications into the pleural space for people suffering from pleural effusions (the build up of fluid in the pleural space).
