The neck itself is the site of lymph node congregation, so abnormalities in the lymph nodes of the neck are common. If the lymph node lesion is caused by lymphadenitis or surrounding inflammatory diseases, the problem is usually not serious and treatment for the primary disease and application of sensitive antibacterial drugs can be considered. If the lymph nodes are soft, with clear borders, movable, and no pressure pain, and the ultrasound shows lymph nodes with dermal medulla and oval aspect ratio less than 1, benign lymph node lesions are also considered in this case, which can be observed on regular follow-up and do not need to be treated. If the lymph nodes are hard, with unclear boundary and poor mobility, or some lymph nodes are fused with each other, and the ultrasound shows unclear demarcation of the lymph nodes and the aspect ratio is greater than 1, it may be lymphoma or metastatic cancer of lymph nodes, which can be further diagnosed by surgical resection biopsy or ultrasound localized puncture biopsy.
