Mediastinal lymph node hyperplasia
Introduction
Introduction Mediastinal tumor The mediastinal tumor is a group of tumors originating from the mediastinum, including thymoma, intrathoracic goiter, bronchial cyst, dermoid cyst, teratoma, lymphosarcoma, malignant lymphoma, pericardial cyst, lipoma, neurogenic tumor. , esophageal cysts, etc., mostly benign. Teratomas are more common in people under the age of 30, and the rest are mostly in the 40s and older. In addition to lymphosarcoma and malignant lymphoma, most of the disease has a good prognosis. (Most of them are lymphatic tumors, which are characterized by mediastinal lymphadenopathy, but can also invade lung tissue to form invasive lesions.
Cause
Cause
A mass formed by abnormalities or acquired causes during embryonic development. Mediastinal tumors are a group of tumors originating from the mediastinum, including thymoma, intrathoracic goiter, bronchial cysts, dermoid cysts, teratomas, lymphosarcoma, malignant lymphoma, pericardial cysts, lipomas, neurogenic tumors, esophagus Cysts, etc., mostly benign. Teratomas are more common in people under the age of 30, and the rest are mostly in the 40s and older.

Most of them are common lymphatic tumors, such as Hodgkin's disease, reticulum sarcoma, lymphosarcoma, etc. are characterized by mediastinal lymphadenopathy, but can also invade lung tissue to form invasive lesions. The short course of the disease progresses rapidly, often accompanied by swollen lymph nodes, irregular fever, hepatosplenomegaly, anemia and so on. X-ray examination showed that the enlarged lymph nodes were located on both sides of the trachea and the lymph nodes on both sides of the hilar were swollen into a mass. The density was uniform and there were large lobes but no calcification. The bronchus often empties and narrows.
Diagnosis
Differential diagnosis
Differential diagnosis of mediastinal lymph node hyperplasia:
1, mediastinal widening: mediastinal widening: mediastinal inflammation, hematoma, abscess, paratracheal lymph node, mediastinal tumor and cyst, superior vena cava and azygotic vein dilation, aneurysm, mediastinal pleural effusion, etc. can make the mediastinum Widening, combined with clinical and medical history, if necessary, tomography, angiography and other inspection methods to determine the reasons for the widening.
2, mediastinal gas: local soft tissue infiltration, is the liquid slowly infiltrated into the soft tissue, human tissue is immersed in abnormal cells or body cells that should not appear under normal circumstances, and some diseased tissue spread to the surrounding phenomenon . Excessive accumulation of substances in the cells or in the interstitium or accumulation of some of the original substances is also called infiltration. Some degeneration or deposition is also called infiltration.
3, mediastinal cyst: cyst of mediastinum is a type of mediastinal masses (mediastinal masses), there are those who belong to the mediastinal tumor (mediastinal tumor), but more people advocate it and the mediastinal tumor separately .
