Bilateral hilar lymph node enlargement refers to the increase in the diameter or volume of lymph nodes at the bilateral hilar sites of the patient’s lungs on imaging. When double hilar lymph nodes are found to be enlarged, it is necessary to further improve the relevant examination, such as enhanced MRI, enhanced CT, etc.. Lymph nodes are distributed in all parts of the body, and enlargement of lymph nodes in both hilar lymph nodes will occur when they are attacked by viral infection, inflammation stimulation, or tumors, such as tuberculosis, pneumonia, lung cancer and other diseases that can lead to enlargement of lymph nodes in both hilar lymph nodes. Patients need to undergo relevant examinations in time, such as enhanced MRI, enhanced CT, biopsy, etc., to clarify the cause of the disease and provide symptomatic treatment. If the patient’s double hilar lymph node enlargement is caused by tuberculosis, anti-tuberculosis drugs such as rifampicin and levofloxacin can be used for treatment. If the enlargement of hilar lymph nodes is caused by pneumonia, it can be treated with drugs such as ribavirin and amoxicillin. If the enlargement of hilar lymph nodes is caused by lung cancer, surgical treatment, radiotherapy, chemotherapy and so on can be carried out. When patients have enlarged lymph nodes in both hilar lungs, they should go to the hospital in time and be treated under the guidance of doctors.
