Lymphatic tuberculosis can die in a few years without treatment, depending on the patient’s physical condition and the severity of the tuberculosis. Lymphatic tuberculosis is a local or systemic toxicity caused by Mycobacterium tuberculosis attacking the lymphatic system, and can also be secondary to intrapulmonary tuberculosis. Patients need a full course, adequate amount and duration of anti-tuberculosis treatment, and most can be cured. Patients with lymphatic tuberculosis are usually not in rapid and fatal danger if they do not seek medical treatment. However, if tuberculosis is not treated promptly and effectively, the disease cannot be controlled and may gradually worsen if the disease is prolonged, which in turn may cause a variety of comorbidities, such as multiple tuberculosis infections throughout the body, and thus affect the survival of the patient. Therefore, patients with lymphatic tuberculosis should be treated with rifampin and isoniazid in a timely manner, and liver and kidney functions and lymph node ultrasound should be reviewed to determine whether the lymph nodes are liquefied.
