title: Imaging of lymphadenopathy in the neck.
abstract: Imaging is playing a major role in the assessment of cervical lymphadenopathy. In infectious disease, the assessment of abscess formation and the relation of the abscess to surrounding vital structures is crucial for its management. In head and neck malignancies, imaging can be helpful for staging. Imaging of the neck for the assessment of nodal metastases can be used to detect occult metastases or to assess operability of palpable metastases. The detection of small occult metastases has limitations, as micrometastases cannot be depicted; however, imaging can fulfill a role in diminishing the risk of occult metastases, and thus influence management. For this purpose a very sensitive technique is necessary. The currently used radiological criteria are not sensitive enough to accomplish enough reduction of the risk of occult metastases; therefore, more sensitive CT and MRI criteria, but especially ultrasound-guided aspiration, should be employed to assess the clinically negative neck.
