The cyst of the lung: types and causes of
Testopodobnymi cysts and lesions in his lungs are the most common. They can be single and multiple, one or double - sided, single-chamber and multichamber. In their origin they are divided into true and false. True cysts of the lung are thin-walled cavitary rounded formations that the inside is lined with bronchial epithelium, and they contain air or clear liquid. All of them are innate, that is, their formation occurred due to violations of the formation of the lung in the embryo. A false cyst is a consequence of undergoing of open and closed lung injury or diseases (tuberculosis, abscess). Such education is limited to a dense fibrous capsule.
Parasitic cyst of the lung is called mainly by Echinococcus (Echinococcus granulosus). From the cyst it is necessary to distinguish abdominal air education (the so-called "bullae"), which arise due to degeneration of lung tissue and development of focal emphysema. Complications of cystic formations are their tears, infection and suppuration. Suppuration may occur in a low intensity form of pneumonia, and pneumonia in an acute form, or lung abscess. At the break of the abscess into the bronchi during cough stands a fetid, purulent sputum, quantity depends on the size of the cyst.
The complication festering cysts of the lung - and lymph system: breaking the wall of education with the flow of air and pus in the pleural cavity. In this case, the patient's condition deteriorates.
Symptoms, diagnosis and treatment of cysts of the lung
Pulmonary cysts can be identified in children and adults. The cyst is small in size can occur without any symptoms. At large (5-6 cm in diameter) cysts appear complaints of pain in the chest, there is a dry cough, sometimes bright with the release of viscous mucus without any smell. The main clinical symptom of the pulmonary cysts of large size is shortness of breath because of the violation of gas exchange.
Large cysts, especially in newborns, accompanied by a severe disorder of blood circulation and breathing, they pose a real threat to life.
For the typical complaints of chest pain, shortness of breath and cough is assigned to the x-ray examination, which diagnosed pulmonary cysts. A more complete picture gives spiral computed tomography that allows absolute to identify lesions in his lungs and distinguish them from benign and malignant tumors and other pathologies. Treatment of cysts of the lung - only operative. When suppuration apply conservative therapy, however, it gives only a temporary effect.
