Lymph nodes on the neck are a kind of filters that protect the body from the spread of pathogenic bacteria, toxins and viruses. Infectious diseases lead to changes in the work and condition of the lymph nodes. For early diagnosis of such disorders it is important to find out whether there is a transformation of the structure of these organs, to determine their mobility, density, size - everything that is indicated by ultrasound of the lymph nodes of the neck. In addition, the study allows you to determine the ratio of tissue components, length and width, echogenicity of lymph nodes.
At what diagnoses ultrasound of the lymph nodes of the neck is prescribed?
The examination in question is recommended for suspected cases:
- syphilis;
- cancer of cervical lymph nodes;
- benign or malignant lymphomas;
- metastases to lymph nodes from other organs;
- tuberculosis;
- pathologies of the thyroid gland;
- diseases of the tonsils;
- visceral mycosis;
- lymphosarcoma ;
- leprosy;
- inflammatory processes in the ears;
- Cesari's disease;
- leukemia;
- abscesses;
- diseases of the salivary glands;
- lymphadenitis ;
- actinomycosis.
Norms for ultrasound of cervical lymph nodes
In most medical publications and textbooks it is indicated that the norm of the size of the lymph nodes of the neck on ultrasound is up to 8 mm, sometimes 1 cm, in diameter. But not all so unambiguously.
Virtually all adults have chronic sluggish diseases, at least herpes, which is borne by about 95% of the world's population. Therefore, experts agree that a small increase in lymph nodes, up to 1.5 and even 2 cm in diameter, can be a variant of the norm in each specific case. To clarify the diagnosis, the structure of the organ tissues, their density, echogenicity and mobility, as well as the presence of concomitant symptoms of the disease, are of more importance.
