The article discusses basic mistakes that can occur during ultrasound imaging of
superficial lymph nodes. Ultrasound is the first imaging method used in the
diseases of superficial organs and tissues, including lymph nodes. The causes of
mistakes can be either dependent or independent of the performing physician. The
first group of mistakes includes inappropriate interpretation of images of
anatomical structures, while the latter group includes, among other things,
similar ultrasound images of different pathologies. For instance, a lymph node,
whether normal or abnormal, may be mimicked by anatomical structures, such as a
partially visible, compressed vein. Lymph nodes in lymphomas may be
indistinguishable from reactive lymph nodes, even when using Doppler option, as
well as morphologically difficult to distinguish from metastases. Metastatic
lymph nodes can mimic e.g. nodular, separated postoperative thyroid fragments, a
lateral neck cyst, chemodectoma (carotid body tumor) or neuroma. The appearance
of lymph nodes in granulomatous diseases, such as tuberculosis or sarcoidosis,
can be very similar to that of typical metastatic lymph nodes or lymphomas.
Anechoic or hypoechoic areas in a lymph node can represent necrosis or metastatic
hemorrhages, but also suppuration in inflamed lymph nodes. Lymph nodes in
lymphomas, metastatic and reactive lymph nodes can adopt the classical
characteristics of a simple cyst. The overall ultrasound picture along with all
criteria for the assessment of a lymph node should be taken into account during
ultrasound imaging. It seems that the safest management is to refer patients
diagnosed with lymph node abnormalities for ultrasound-guided targeted fine
needle aspiration biopsy followed by a total lymph node resection for
histopathological examination in the case of suspected lymphoma.
