A

ssessment of lymph nodes (LN) is of great clinical importance, especially in oncological practice, as it is a criterion for staging the oncological process and a necessary component in developing patient treatment strategy. The inguinal LN are involved in the outflow of lymph from the pelvic organs, lower extremities, skin of the lower abdomen, lower back and gluteal region. They respond to any inflammatory processes and also serve as a barrier to the expansion of metastatic emboli. The formation of images of lymph nodes using various imaging methods, such as ultrasound (US), computed tomography, magnetic resonance imaging has led to some contradictions in the description of the picture of inguinal LN not only in various pathological conditions, but also in normal conditions. Understanding the normal visualization of LN requires further study. This article is devoted to the study of superficial inguinal LN.

Purpose. To evaluate the parameters of unchanged superficial inguinal LN and identify the features of their structure according to ultrasound results.

Materials and methods. The results of ultrasound examination of 637 inguinal LN in 98 healthy individuals without diseases of the pelvic organs were studied: male – 46, female – 52 people. A total of 30 people under the age of 40, after 40 years – 68 people.

Results and discussion. Superficial inguinal lymph nodes normally reached an average length of 30.5±12.1 mm, an average transverse size of 6.6±2.3 mm and cortical thickness of no more than 3 mm. In the same person, lymph nodes of a standard oval shape with smooth contours were determined; extended lymph nodes of segmental or ribbon-like shape with mono- and multi-lobulated contours, of various sizes. Small lymph nodes up to 10 mm in size, with a rounded shape, with preserved differentiation of lymph node structures, had an L/S index <2.0, which contradicted the literature data and required a comprehensive assessment in B-mode and color doppler.

Conclusion. The identified features of superficial inguinal lymph nodes require a comprehensive ultrasound assessment, especially for sizes up to 10 mm, which must be taken into account when searching for metastatically altered inguinal lymph nodes.
