How is mediastinal tumor caused?

summary

Tumor disease is a kind of disease endangering people's life safety. If not treated as soon as possible, patients will lose their lives. Experts point out that mediastinal tumors are the highest incidence rate of neurological tumors. So, how is mediastinal tumor caused? Let's take a look.

How is mediastinal tumor caused?

Mediastinal inflammation, hematoma, abscess, paratracheal lymphatic tuberculosis, mediastinal tumors and cysts, dilatation of superior vena cava and azygos vein, aneurysms, mediastinal pleural effusion can make mediastinal shadow widened. Combined with clinical and medical history, tomography and angiography should be performed when necessary to determine the causes of mediastinal shadow widened. When the pressure in one side of the chest increases, such as a large amount of pleural effusion or tension pneumothorax, one side of emphysema or huge space occupying lesions can push mediastinum to the contralateral side. On the contrary, when the pressure in one side of the chest decreases or the fibrous changes contract, such as atelectasis, pleural thickening, and a large number of fibrous changes in the lung, the mediastinum is pulled to the affected side. When the bronchi are partially obstructed, the mediastinum can swing to the left and right during breathing (the mediastinum moves to the healthy side during exhalation, and to the affected side during inspiration) due to the uneven pressure of the thoracic cavity on both sides during breathing.

Mediastinal tumors are divided into primary and metastatic. Metastatic tumors are more common, and most of them are mediastinal lymph node metastasis, while hematogenous metastasis is very rare. There are many types of primary mediastinal tumors, usually including tumors and cysts produced by various tissues and structures in the mediastinum. Their common manifestations are mass lesions. Many tumors lack characteristic manifestations, so it is difficult to differentiate them.

The common primary mediastinal tumor usually has its predilection site. The analysis of the location and shape of the tumor is of certain significance for the diagnosis, and the classification of the tumor can often be inferred. According to the shape and density of the tumor, benign and malignant manifestations can be roughly distinguished. Lobulated and irregular margin are often malignant manifestations. Most of the round or oval masses with sharp edge, smooth and uniform density are benign. The density of teratoid tumor may be uneven, including bone or tooth. The arc or ring calcification along the edge of the mass indicates that the mass is cystic or solid, and has tumor degeneration. It is important to pay attention to the relationship between tumor and its surrounding organs for studying the location and source of tumor. Thyroid tumors can move up and down with swallowing; The tumor near the trachea narrows and displaces the trachea under normal pressure. In the bone adjacent to the tumor, there may be compressive bone defect with neat boundary, which is the manifestation of benign tumor, and erosive bone destruction is the sign of malignant tumor.

matters needing attention

When tumor disease appears in us, whether it is benign or not, we must remove it through surgery, so as to avoid adverse consequences. Develop good living habits, do regular physical examination, timely find out the problems of the body, do not drag a minor illness into a serious illness, for patients, in addition to a good mood, but also actively treat, do surgery, cooperate with the doctor to complete the treatment, eat more alkaline food, promote the recovery of body immunity
