Normal physiological conditions may cause the cervical lymph nodes to show punctate blood flow signals, which are generally not serious, while the phenomenon may be more serious when caused by factors such as lymphadenitis and lymphoma.
1. Normal physiological phenomenon: lymph nodes are supplied with blood in order to maintain normal physiological functions, and it is normal to find that cervical lymph nodes show punctate blood flow signals during examination.
2. Lymphadenitis: this disease is related to pathogenic microbial infection and other factors, cervical lymphadenitis will stimulate the body to produce immunopathology, the blood circulation around the lymph nodes will be accelerated, and punctate blood signals of the lymph nodes will appear in the examination.
3. Lymphoma: this disease is related to factors such as immunity and infection, tumor tissues need blood supply, and punctate blood flow signals will appear in lymph nodes in the neck when the lymph nodes suffer from this disease.
Punctate blood flow signals in the lymph nodes of the neck need to be combined with other tests to determine the disease and then carry out relevant treatment.
