Pulmonary hypertrophy is a condition in which some parts of the body become swollen, enlarged and painful because of a lung disease. Common pulmonary hypertrophy disorders include pulmonary hypertrophic osteoarthropathy. Pulmonary hypertrophic osteoarthropathy is a clinical imaging syndrome that includes pestle and mortar fingers (toes), long bone osteoarthritis and arthritis, and the onset is mostly associated with pulmonary lesions. So, what tests should be done for pulmonary hypertrophy caused by tuberculosis? The following is a brief introduction: 1, PPD skin test or blood anti-tuberculosis antibody test: a strong positive PPD skin test is considered to have recent Mycobacterium tuberculosis infection. 2. Chest X-ray and chest CT to clarify whether there is pulmonary tuberculosis and mediastinal lymph node tuberculosis, which can help the differential diagnosis with lung cancer. 3, sputum examination, sputum smear or collection of bacteria to find antacid bacteria, culture of sputum tuberculosis bacteria and drug sensitivity test, the purpose is to find the pathogen (Mycobacterium tuberculosis), drug sensitivity test results can indicate whether drug-resistant tuberculosis, that is, which drug treatment may be effective and which drug may be ineffective. If necessary, cancer cells are looked for in order to differentiate it from lung cancer. 4.Fiber bronchoscopy is needed when the patient has a severe cough, the distribution of lesions in the lung appears to spread along the bronchus, or the lesions in the lung need to be differentiated from other diseases such as lung cancer. 5.When the differential diagnosis is needed with pneumonia, anti-inflammatory treatment is required, and the chest X-ray or chest CT is repeated after two weeks of anti-inflammatory treatment. 6.When the diagnosis of intrapulmonary lesions is still not clear after the above tests, lung aspiration biopsy is also required.
