Ultrasound diagnosis of non-mass-like breast lesions

Many breast lesions show non-mass-like lesions instead of presenting with nodules or lumps. High-resolution ultrasonography can identify the non-mass-like breast lesions which may be ignored in clinic. This review elucidates various ultrasonographic findings of the non-mass-like breast lesions, and the correlation of ultrasonographic findings and sonographicpathologic by elastography, Doppler techniques and other radiological technologies.
