Mediastinal tumor

A clinical performance. Common symptoms are as follows : (1) respiratory symptoms : chest tightness, chest pain usually occurring in substernal or on the side of the chest. Most invasive malignant bone or nerve, the pain is intense. Cough often trachea or lungs caused by compression, see less of hemoptysis. (2) neurological symptoms : due to the compression or nerve erosion have symptoms : If the tumor and the phrenic nerve can cause hiccups and diaphragm palsy; If violations of the recurrent laryngeal nerve tumors, can cause hoarseness; If sympathetic involvement can have documented Syndrome; intercostal nerve erosion, may have chest pain or paresthesia. If spinal nerve compression caused paralysis of limbs. (3) infection symptoms : If tumor or cyst rupture affected bronchial infection or lung tissue, then there was a series of symptoms of infection. (4) compression symptoms : Superior vena cava pressure, common in on the mediastinal tumor, was particularly prevalent in malignant thymoma and lymphoid malignancy. Esophagus, trachea pressure, and there may be short breath or hypopharyngeal obstruction and other symptoms. (5) special symptoms : teratoma breaking into bronchial patients cough and sebum from the hair. Bronchogenic cyst rupture and bronchial similarities performance bronchopleural fistula symptoms. A handful of intrathoracic thyroid cancer patients, the symptoms of hyperthyroidism. Thymoma patients, sometimes accompanied by symptoms of myasthenia gravis. Diagnosis (1) conventional X-ray examination is lateral chest X-ray photographs and fluoroscopic examination, the tumor size, location and shape. Density and calcification or pulsate. With respiratory whether deformed, or with swallowing and moved up and down. According to these findings, and clinical symptoms, the initial diagnosis can be made. Further inspection methods : bronchial angiography, CT angiography, or wave imaging, angiography and mediastinal Pneumocolon other. (2) attending microscopic examination of chest films or stratification indicated the trachea and esophagus shift, it should make the trachea and esophagus microscopic examination, in order to understand whether there is a cavity tumor. (3) radioisotope examination of suspected intrathoracic thyroid cancer patients and can be used as a tracer radioactive iodine inspection, the majority will be positive results. (4), located in the percutaneous biopsy of peripheral masses, in a television under fluoroscopic positioning, pilot puncture biopsy examination, to be histological diagnosis. (5) pilot clinical radiation therapy for cancer patients, except not, try a small amount of radiation therapy, After treatment reduced tumor can be indirectly proven diagnosis, because as lymphosarcoma after radiotherapy will be a rapid response. (6) examination of biopsy or axillary Au neck superficial lymph nodes, viable biopsy pathologic examination. (7) X-ray computer layered scan (CT) (8) exploratory thoracotomy or sternotomy incision longitudinal split, tumor resection or biopsy pathologic examination confirmed the diagnosis and timely surgical treatment. 3. Differential Diagnosis : all mediastinal tumor lesions should be differentiated with the following (1) aortic aneurysm or innominate artery aneurysm : in the ascending aorta and aortic arch and parts of the innominate artery aneurysm, and the need to differentiate mediastinal tumor. X-ray, can see connected with the aorta, is not easy to separate and expand beat block video. X-ray radiography or wave and serum testing will contribute to the rehabilitation Fahrenheit differential diagnosis, and the necessary conditions permit, for retrograde aortic angiography. (2) paravertebral abscess : paravertebral abscess at the spine on both sides, is symmetrical. X-ray inspection may show bone destruction and deformity. Performance can be combined with clinical diagnosis. (3) central lung cancer : in favor of the side of the hilum, patients often hemoptysis, irritating cough and expectoration. Layered radiography, bronchography contrast, sputum cells contribute to the investigation pathological diagnosis. (4) mediastinal lymph nodes : more common in young patients often weak, night sweating, weight loss, fever and other symptoms. X-ray revealed was lobulated or nodular shadows, sometimes within the tumor calcification, lung lesions may have tuberculosis, tuberculin test positive for more. Treatment of identified mediastinal tumor, malignant and as high as 30% because of the gradual growth to be near the organs of oppression, resulting in obstruction. Cystic mass and possible rupture, infection, or bronchial linked with the incidence of acute asphyxia, caused the death of the patients. Therefore, regardless of all mediastinal tumors are asymptomatic, or whether there have been changes in malignant tumors, with the exception of malignant lymphoma, the patient should be allowed to, the purposes of surgical resection. Malignant tumors of lymphocytes to the appropriate radiotherapy.
