The probability that an encapsulated pleural effusion will absorb on its own without treatment is small, and only some of the effusions that are small can be absorbed, so you need to consult your doctor for details.
The so-called encapsulated pleural effusion refers to the pleural effusion that occurs between the pleura and the chest wall membrane due to lung diseases such as pneumonia and tuberculosis. It is called an encapsulated effusion because it is wrapped. It is relatively unlikely to absorb on its own due to the presence of underlying disease and the fact that it is not directly connected to the lung tissue.
In the case of an encapsulated pleural effusion, the primary disease should be treated promptly, and pleural puncture and drainage should be performed on this basis. Only some patients with small amounts of fluid are able to self-absorb, with no fixed probability. Therefore, it is necessary to consult a doctor in time, under the guidance of the doctor for examination and treatment, subject to the doctor’s opinion.
