Cervical lymph node enlargement. In young people, any infection in the head and neck can cause lymph node enlargement, the most common site being the jugulodigastric nodes located just below the angle of the jaw (a). In older patients, it is important to exclude metastases from head and neck cancer. Other causes of cervical lymphadenopathy include TB and lymphoma. A systematic approach to examining all areas of the neck is important in the general examination process. Adenopathy can be demonstrated on CT scanning, which is commonly used in the staging of lymphoma.
NB lymphoma staging includes bone marrow aspiration, assessment of liver and spleen and whole body scanning to assess lymphadenopathy.
