What does subpleural hemorrhage mean?

Subpleural hemorrhage refers to bleeding that occurs beneath the pleura, which is the thin membrane surrounding the lungs. This condition can result from various causes, including trauma, infection, or malignancy. Clinically, it may be detected on imaging studies such as chest X-rays or CT scans, often appearing as localized areas of increased opacity. Symptoms can vary depending on the underlying cause and the extent of the hemorrhage.
