A 37-year-old female with huge mass in the left breast; (A, B) The location of the tumor on enhanced MRI; (C); Sonographic appearance of the tumor on 2D-Ultrasound; (D) Contrast-enhanced ultrasound showed homogeneous hyperenhancement of the tumor during the arterial phase; (E) During ultrasound-guided microwave ablation; (F) The area of ablation showed no enhancement in arterial phase and venous phase after ablation; (G); The skin of the breast was slightly ecchymosis after ablation, and the appearance of the breast was intact; (H, I) After 10 months of follow-up, two-dimensional ultrasound showed that the mass was significantly reduced, and CEUS showed that there was no enhancement in the arterial phase and venous phase of the ablation area.

Imaging-Reporting and Data System (BI-RADS) category 4. It had morphological rules and circumscribed margins, and was coincident with the location described through US ( Figures 1A, B ). The 2D-Ultrasound Contrast-enhanced ultrasound (CEUS) was performed using Mindry Resona 7 ultrasound system to discover the optimal ablation puncture path ( Figures 1C, D ). When the hyperechoic area was completely covered by ablation, CEUS examination was performed, and there was no enhancement in the ablation area, indicating that the ablation was completed. ( Figures 1E, F ). There was slight ecchymosis, redness and swelling on the skin of the operation area after operation ( Figure 1G ), which disappeared completely after 4 weeks. The ablation area was completely ablated without recurrence, and the lesion was significantly smaller than before ( Figures 1H, I ).
Histological sections revealing monotonous spindle cell proliferation, necrosis or mitotic figures found. (A, B) Histologic image of leiomyoma. (H&E, x 400).

The patient was diagnosed as breast leiomyoma by pathological examination via sonography guide core needle biopsy ( Figure 2 ).
