Effusion

Effusion is a medical term that refers to an abnormal accumulation of fluid in a body cavity. This can occur in various parts of the body, including the lungs (Pleural effusion), heart (Pericardial effusion), and joints (Joint effusion).

Causes

Effusions can be caused by a variety of conditions, including inflammation, infection, cancer, and trauma. The type of fluid that accumulates can vary depending on the cause. For example, in infections, the fluid may be pus (pus), while in cancer, it may be bloody (hemorrhagic effusion).

Symptoms

The symptoms of an effusion can vary depending on its location and size. For example, a pleural effusion may cause shortness of breath, while a joint effusion may cause pain and swelling. In some cases, an effusion may not cause any symptoms and may only be discovered during a medical examination or imaging test.

Diagnosis

Effusions are typically diagnosed through imaging tests, such as ultrasound, CT scan, or MRI. In some cases, a sample of the fluid may be taken for analysis to help determine the cause of the effusion.

Treatment

The treatment for an effusion depends on its cause. This may involve treating the underlying condition, such as giving antibiotics for an infection or chemotherapy for cancer. In some cases, the fluid may need to be drained to relieve symptoms.
