In screening mammography, intraamammary lymph nodes (IMLN) are one of the most typical benign findings. However, atypical IMLN characteristics such a reduced or missing hilum, thickened cortex, uncircumscribed edges, an increase in size, or an interval change call for further investigation or pathologic examination to rule out cancer.
As a response to cutaneous inflammation as well as metastatic involvement, normal intramammary lymph nodes may develop or grow in the breast. When they do, they might notice a mass with a diameter of more than 1 cm that is spherical, clearly defined, homogeneous, and high density.
The term "intramammary lymph nodes" refers to lymph nodes that are encircled by breast tissue. As many as 9.8% of operable breast tumors have metastases in this node, making them a possible site for regional breast cancer dissemination.
