A 31-year-old woman with a BI-RADS 3 fibroadenoma. (a) Conventional US detected a hypoechoic, solid mass with a well-defined boundary and a transverse axis diameter of 16 mm located in the left breast; color Doppler imaging showed the lesion to be vascularized (Grade II); (b) on elastography, the lesion was classified as Itoh score 3; (c) gray-scale imaging during ablation showed a hyperechoic mass with ill-defined boundaries; (d) conventional US performed at the 3-month follow up showed a heterogeneous hypoechoic mass with a transverse axis diameter of 10 mm; (e) on elastography at the 3-month follow up, the lesion was found to be softer than before ablation with a Itoh score of 2; (f) the lesion is hardly visible on conventional US imaging at the 12-month follow up
