Although the role of high resolution ultrasound (US) in evaluating cervical nodes is well established, it is often combined with fine needle aspiration cytology (FNAC). As a result, US appearances that help in distinguishing the various causes of cervical adenopathy are often overlooked and not emphasized. The aim of this study is to re-emphasize to the sonologist the US clues that may help in differentiating the aetiology of abnormal cervical nodes. We, therefore, present the spectrum of US appearances of lymph nodes. One hundred and forty patients (702 abnormal nodes) with known pathology were compared with 100 normal subjects (1211 nodes). After identifying an abnormal nodes, US features that further help in distinguishing between the various pathologies are the distribution of lymphadenopathy, echogenicity, calcification, distal enhancement, intranodal cystic necrosis, matting and soft tissue oedema.
