There is a major distinction between congenital and acquired lung cysts, with congenital usually having no obvious symptoms, and acquired may have lung symptoms. Pulmonary cysts represent cystic lesions of varying sizes of gas and fluid inside the lungs, and most congenital pulmonary cysts have no obvious symptoms. In the case of acquired cysts, hemoptysis, coughing, coughing up purulent sputum, and dyspnea may occur, mainly due to acquired secondary infections, especially lung infections. If there are symptoms of lung cysts, it is necessary to take symptomatic treatment, and if necessary, surgery can be chosen. If lung cysts are asymptomatic, regular follow-up is needed and no special treatment is required. Patients with pulmonary cysts are advised to consult a doctor in time to clarify the condition of their pulmonary cysts, and then choose whether to take treatment according to their individual situation and formulate appropriate treatment plans under the guidance of the doctor.
