Summary: | 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. |
