Physical examination: to determine whether there are abnormalities in the patient’s chest through visual examination, percussion, auscultation, etc., such as chest enlargement, bulging, and the presence of superficial lymph or lumps, etc.2. X-ray examination: the chest phase reveals that there is a huge mass in the mediastinal region with a smooth silhouette, and the somatic phase reveals that there is a chorionic calcified shadow in the mass as well as a middle bronchus and other mild compression and narrowing. 3. CT examination: observe the degree and size of mediastinal lymph node hyperplasia and whether infiltration and metastasis occur in the surrounding tissues.4. Puncture examination: clarify the nature of hyperplastic lymph nodes and prepare for determining the treatment method.5. Serological examination: serological examination suggests that lactic acid dehydrogenase is elevated, which is highly suspicious of the above mentioned lesions.
