Pleural Effusion
Diagnosis of Pleural Effusion
Chest x-ray and/or ultrasonography Laboratory tests done on a sample of the fluid Sometimes computed tomography (CT) Achest x-ray,which shows fluid in the pleural space, is usually the first step in making the diagnosis. However, small amounts of fluid may not be visible on a chest x-ray. Ultrasonography of the chestcan also be done to help doctors identify small accumulations of fluid. Thoracentesis None If these tests cannot identify the cause of the pleural effusion, other tests may be done. more clearly shows the lung and the fluid and may show evidence of pneumonia, a mediastinal mass, a lung abscess, or a tumor that could be causing fluid to accumulate. Sometimes a radiopaque dye is injected during CT (CT angiography or venography) to look for problems with the pleura or with blood vessels, including Pulmonary Embolism (PE) . Thoracoscopy None
