Ultrasound of malignant cervical lymph nodes - Cancer Imaging Ultrasound of malignant cervical lymph nodes - Malignant lymph nodes in the neck include metastases and lymphoma. Cervical nodal metastases are common in patients with head and neck cancers, and their assessment is important as it affects treatment planning and prognosis. Neck nodes are also a common site of lymphomatous involvement and an accurate diagnosis is essential as its treatment differs from other causes of neck lymphadenopathy. On ultrasound, grey scale sonography helps to evaluate nodal morphology, whilst power Doppler sonography is used to assess the vascular pattern.

OBJECTIVE. Sonography is a useful imaging tool in the evaluation of cervical lymph nodes. Gray-scale sonography and color and power Doppler sonography are commonly used in clinical practice. This article documents the common sonographic appearances of different causes of cervical lymphadenopathy.CONCLUSION. The sonographic appearances of normal nodes differ from those of abnormal nodes. Sonographic features that help to identify abnormal nodes include shape (round), absent hilus, intranodal necrosis, reticulation, calcification, matting, soft-tissue edema, and peripheral vascularity.

Assessment of neck lymph nodes is essential in patients with head and neck cancers for predicting the patient’s prognosis and selecting the appropriate treatment. Ultrasonography is a useful imaging tool in the assessment of neck lymph nodes. ...
