Can axillary lymph nodes be seen on ultrasound?

Introduction

Axillary lymph nodes are an integral part of the lymphatic system and play a crucial role in filtering and trapping foreign substances, such as bacteria and cancer cells, from the upper limbs, chest, and breast.

Ultrasound Imaging

Ultrasound imaging, also known as sonography, utilizes high-frequency sound waves to produce real-time images of the body's internal structures. It is a non-invasive and safe method that has proven to be useful for various medical applications.

While axillary lymph nodes are not typically visible in normal ultrasound examinations, they can be detected under certain circumstances.

The Role of Ultrasound in Evaluating Axillary Lymph Nodes

Physicians often employ ultrasound to evaluate axillary lymph nodes in patients with suspected breast cancer or other pathologies. Ultrasound can assist in determining their size, shape, consistency, and any abnormalities that may indicate disease.

Furthermore, ultrasound can be used to guide needle biopsy procedures, in which a small tissue sample is extracted from a lymph node for laboratory analysis. This technique aids in establishing a definitive diagnosis and subsequent treatment planning.

Factors Affecting Visibility

Several factors influence the visibility of axillary lymph nodes on ultrasound:

  • Size: Smaller lymph nodes may be harder to detect, while larger ones tend to be more visible on ultrasound.
  • Echogenicity: Lymph nodes can exhibit varying echogenicity, depending on their composition and pathology. Hyperechoic nodes appear brighter on ultrasound, while hypoechoic nodes display decreased brightness compared to surrounding tissue.
  • Surrounding Tissue: The presence of adjacent structures like blood vessels or fatty tissue can affect the visualization of axillary lymph nodes.
  • Pathology: Inflammatory conditions or the infiltration of cancer cells may cause lymph nodes to enlarge, change shape, or display abnormal echogenicity, making them more evident on ultrasound.
Conclusion

In conclusion, while axillary lymph nodes may not be ordinarily visible on ultrasound, this imaging modality serves as a valuable tool in evaluating them for potential abnormalities. Ultrasound allows physicians to assess the size, shape, and characteristics of lymph nodes, enabling accurate diagnosis and appropriate treatment decisions.

We hope this article has provided you with comprehensive information on the visibility of axillary lymph nodes on ultrasound.
