Multiple lymph node echoes in the neck may be caused by infections, tuberculosis or tumor diseases. 1. Infection: Thyroiditis, tonsillitis, upper respiratory tract infection caused by bacterial or viral microbial infections can lead to lymph node hyperplasia and enlargement. After treatment with appropriate antibiotics or antiviral drugs, the lymph nodes can be reduced and return to normal. 2. Tuberculosis: Tuberculosis caused by Mycobacterium tuberculosis infection can cause low-grade fever and lymph node enlargement. It should be treated with anti-tuberculosis drugs such as isoniazid and rifampicin in time. 3. Tumor disease: metastatic tumor of thyroid cancer, breast cancer, lung cancer and lymphoma will invade and infiltrate the lymph nodes in the neck and proliferate and differentiate in the lymph nodes, resulting in lymph node increase and enlargement. Pathological biopsy should be performed in time to clarify the nature of the lesion, and symptomatic treatment or radiotherapy should be performed in time. It should be noted that when there are multiple echogenic lymph nodes in the neck, it is necessary to go to the hospital in time for examination and treatment under the guidance of the doctor.
