One case was admitted to our hospital. The literature is now reported as follows: The patient is 24 years old. Five months ago, I fell to the right chest with a bicycle and felt pain in my right chest. A chest radiograph taken at a local hospital found a shadow of the left lower lung and was diagnosed as tuberculosis. After three months of anti-TB treatment review, the left lung block shadow increased, and transferred to our hospital for treatment. The patient often feels chest pain, chest tightness, and sometimes coughing, but no hemoptysis, no fever, night sweats, and fatigue. There is no history of tuberculosis and cancer in the family. Physical examination: generally good condition, except auscultation of lower left lung breath sounds
