A normal ultrasound of enlarged lymph nodes means that the lymph nodes are enlarged and no structural abnormalities are seen on the ultrasound. This is not necessarily a case of it being fine. Common causes of enlarged lymph nodes include lymphadenitis and connective tissue disease, metastatic cancer, lymphoma, lymphoblastic leukemia, and other factors. On ultrasound, only enlarged lymph nodes may be found, but the structure is abnormal. Lymph nodes that are enlarged and have no structural lymphatic abnormality on ultrasound may also be free of disease. In some cases, the lymph nodes may not return to their original size due to fibrous tissue encapsulation after the inflammation has subsided. The most accurate test to determine whether an enlarged lymph node is benign or malignant is a cytologic biopsy, and ultrasound is not able to confirm the diagnosis. Of course, if the body does not have any uncomfortable symptoms, and other laboratory tests are normal, you can follow up once every three to six months, and review the ultrasound to dynamically observe the changes of the lymph nodes.
