Pleural disease

Pleural disease affects the pleural space, the small gap between the two lining membranes around the lungs. Normally this space contains a tiny amount of fluid to help the lungs slide as you breathe. Problems here include:

- Pleural effusion: too much fluid in the space
- Pneumothorax: air in the space
- Pleural thickening: scarring that can make breathing harder
- Tumors: can be benign or malignant

Pleural tumors can be benign, such as solitary fibrous tumor, or malignant. The most well-known malignant pleural cancer is mesothelioma, which is strongly linked to asbestos exposure. Many pleural cancers are not primary; they spread from nearby tissues or from other cancers, especially lung or breast cancer. Symptoms may include chest pain, shortness of breath, cough, or fever. Diagnosis uses imaging like X-rays or CT scans, analysis of pleural fluid, and sometimes biopsy. Treatments vary and may include draining fluid, surgery, chemotherapy, or radiation.
