Radiologists can designate nonmass lesions on breast ultrasound

By Amerigo Allegretto

Breast radiologists achieved moderate to substantial interreader agreement for classifying nonmass lesions on ultrasound.

December 9, 2025

Images depict a 50-year-old woman with a lesion detected during screening ultrasound. (A) Transverse and (B) longitudinal images reveal a 0.5-cm hypoechoic lesion (arrow) in the left breast. (C) Transverse color Doppler ultrasound image does not show an increase in vascularity. Two readers classified the lesion as a mass, whereas two others categorized it as a nonmass lesion, leading to its designation as a controversial nonmass lesion. Ultrasound-guided core needle biopsy and subsequent pathologic examination confirmed a nonproliferative breast change.
