Patient: CT shows: symmetrical thorax, mediastinum in the center, enlargement of both pulmonary hilum, narrowing of bronchi with pressure in both lungs, multiple enlarged lymph nodes in the mediastinum and both pulmonary hilum, multiple nodular soft tissue density shadow in the left interlobular pleura, and a small amount of fluid density shadow in the bilateral thoracic cavity. Current physical status: left chest tightness, white sputum, chest discomfort. In Shenyang a large hospitalization treatment for half a month did not see significant improvement. I’m not in the hand for the time being. I’ll send it to you in a few days. Hospital thoracic surgery: the most common causes of mediastinal lymph node enlargement include: tuberculosis, nodular disease, lymphoma. The treatment options are: anti-tuberculosis treatment, hormone therapy, chemotherapy. The most effective diagnostic tool is mediastinoscopic mediastinal lymph node biopsy, and the treatment plan is based on the biopsy results. There are not many hospitals in China that perform mediastinoscopy, and the Department of Thoracic Surgery of Shanghai Pulmonary Hospital is one of the first units to perform mediastinoscopy.
