Misleading appearance in cervical lymph node US diagnosis – a report on sarcoidosis, Warthin tumor and squamous cell carcinoma metastases

Abstract

Ultrasonography, with its various techniques (grey-scale, color Doppler, sonoelastography) offers many signs for the differentiation between benign and malignant neck lymph nodes. In spite of recent progress, the US appearance may be misleading. We present three cases in which the ultrasonographic appearance of the lymph nodes was misleading as compared to the final diagnosis established by histopathology.
