- dyspnea). Many pleural effusions cause no symptoms but are discovered during the physical examination or seen on a chest x-ray, which is the most convenient way to confirm the diagnosis. Many conditions are capable of causing pleural effusion, including heart failure and uremia (kidney failure), hypoalbuminemia (low levels of albumin in the blood), infections (TB, bacterial, fungal, viral), pulmonary embolism, and malignancies (metastatic tumors, Hodgkin disease, mesothelioma). Despite extensive evaluation, the causation of a pleural effusion is not established in about 20% of cases. The term "effusion" comes from the Latin "effusio" meaning a pouring out. A pleural effusion is thus, literally, a pouring out of fluid into the pleural space.
