Shear wave elastography (SWE) is a relatively new and highly effective method to reveal mechanical features of tissue by demonstrating quantitative elasticity value. The morphological features including margin of the lesion, orientation, shape and border are considered in differentiation of breast lesions on USG. It is a known fact that malignant lesions are usually palpated as a hard mass in the physical examination. A qualitative broad information can obtain about the tissue elasticity by integrating SWE examination into the classical USG evaluation. We reported the finding of SWE examination in breastfeeding patient with breast malignancy in addition to magnetic resonance imaging (MRI) and ultrasonography (USG) findings.
