Presentation
Mastalgia
Patient Data
An oval-shaped hypoechoic structure is seen among the breast parenchyma with central fatty region representing an intramammary lymph node.
The blood vessels are entering the hilum of the intramammary lymph node and showing flow on color Doppler.
Case Discussion
Intramammary lymph nodes are one of the most common benign findings (BIRADS 2). They are seen as circumscribed oval or reniform non-calcified structure with central fatty hilum. They have a predilection for the upper and outer quadrant of the breast. They are defined as lymph nodes that should be surrounded by breast tissue on all sides.
