“Mimic breast cancer” involves irregularly shaped hypoechoic areas with Doppler flow signals suggesting invasive cancer on breast ultrasonography in one section view that are non-reproducible in others. The ultrasonographic features in four cases of mimic breast cancer are discussed. These findings may represent areas where a penetrating breast artery emerges through the mammary zone. The cancer-like appearance may be due to irregular mammary zone disconnection by the penetrating artery and perivascular fat tissue, and shadowing from arteries adjacent to the anterior mammary fascia. Such lesions may be interpreted as breast cancer by inexperienced examiners, and are associated with risk of vessel injury as a result of needle biopsy.
