Lymph node metastasis is an important prognostic factor in cases of carcinoma breast. In this pictorial essay, various sonographic and elastographic signs of lymph node metastasis are described with classical images.
Axillary lymph node metastasis is an important prognostic factor in early-stage breast cancer and remains crucial on which individual treatment decisions are made.1 Mammography has its limitations in detecting metastatic lymph nodes because the entire axillary region cannot be adequately evaluated with this method. Positron emission tomography combined with computed tomography and magnetic resonance imaging do not have a place in routine staging because of higher costs and possibility of side effects.2 Ultrasonography (USG) is the most widely used imaging method for detection of axillary lymph node metastasis and for their characterization.3

Metastasis to axillary lymph node is an important factor in the prognosis of early-stage breast cancer and crucial for decision-making in management. There are many classical gray-scale and elastographic features that predict metastasis to axillary lymph node. These features are discussed in brief and classical images are illustrated in patients of breast cancer. These features help in early detection of lymph node metastasis.
