Neck lymph node ultrasound shows a little liquefaction within the lymph nodes means that there is liquid echogenicity within the lymph nodes, suggesting that there is inflammation, tuberculosis infection and lymphatic metastasis of lymphoma or malignant tumors and other causes. 1. Inflammation: If inflammation stimulation leads to lymphadenitis, resulting in lymph node enlargement. When there is suppuration and necrosis of lymph nodes, ultrasound examination can find liquefaction of lymph nodes. 2. Tuberculosis infection: If infected by tuberculosis, the lymph nodes will undergo suppurative changes, causing necrosis of their own tissues, and will also show a little liquefaction within. 3. Lymphoma or malignant tumor lymphatic metastasis: when the enlarged lymph nodes are partially necrotic, the internal echogenicity can be found to be uneven through ultrasound, which can also be accompanied by a little liquefaction. If the above situation occurs, the patient should pay attention to it, and suggest to do pathology, laboratory tests and other tests to make a clear diagnosis, and then timely treatment, do not be negligent, so as not to delay the condition.
