2. Neoplasms of the mediastinum
3. clinical picture of mediastinal tumors
4. mediastinal lymphadenopathy
Mediastinum -this anatomical space, the middle of the chest.This limited space behind the spine and front - sternum.On either side of the mediastinum are pleural cavity.Currently anatomists divide the body on the bottom, top, back, middle and anterior mediastinum.
posterior mediastinum in front of the limited pericardium and trachea, and in the back - the spine.This department is the body thoracic duct, descending aorta, and hemiazygos unpaired vein, the esophagus and the posterior mediastinal lymph nodes.
Structure middle mediastinum: vena cava, heart, brachiocephalic trunk and the brachiocephalic vein, trachea, main bronchus, pulmonary artery and vein, ascending aorta, aortic arch and diaphragmatic veins.
anterior mediastinum rear limited brachiocephalic trunk, brachiocephalic vein an
Lower mediastinum is divided into the back, middle and front parts.It is limited by the upper edges of the pericardium and diaphragm.
upper mediastinum has all the anatomical structures that are above the upper edge of the pericardium.It is limited to the upper aperture of the sternum and the line drawn between the intervertebral disc Th4-Th5 and the angle of the chest.
above anatomical spaces are as true mediastinal tumor, and excellent localization, course and aetiology cyst and tumor diseases.Every new formation of this body is formed from tissues of different origin, joining only anatomical boundaries.
mediastinal neoplasms are subdivided into:
Judging by responses doctors, including special mediastinal tumors are detected, usually in the middle and young age.Neoplasms of the body may be a long time to manifest itself.They are found in most cases to prevention trials.
main symptoms that characterize the disease of the mediastinum are:
Later stages of the aforementioned organ disease characterized by general weakness, fever, swelling of the limbs, heart rhythm disturbances and artralgicheskim syndrome.
Treatment of mediastinal tumors exclusively surgical.
lymphadenopathy (swollen lymph nodes) the mediastinum observed, usually in lymphomas, metastatic carcinoma and some other non-neoplastic diseases (tuberculosis, sarcoidosis, and so on.).
